A group of young people were asked how many times they have been stopped and questioned by the police:

                                                Non-White            White

Mean # of Stops               4.95 .99

Varriance 4.11 6.08

Sample size 155 310

We need t-test in order to determine if Non-White and White young people are stopped by the police at the same rate. You should be sure to specify, and evaluate, both the Null and Alternative Hypotheses.

A researcher reported the results of a telephone poll of 1000 adult Americans. The question posed of those who were surveyed was: "Should the federal tax on cigarettes be raised to pay for health care reform?" Of 600 non-smokers, 362 said yes. Of 400 smokers, 80 said yes. What is the test statistic, at alpha = .05, if you want to determine that the proportion of non-smokers who said yes is greater than the proportion of smokers who said yes?

In a population of Siberian flying squirrels in western Finland, assume that the the number of pups born to each female over her lifetime has mean ?=3.66 and standard deviation ?=2.9598. The distribution of squirrel pups born is non‑normal because it takes only whole, non‑negative values.

Determine the mean number of pups, x¯, such that in 70% of all random samples of such squirrels of size ?=40, the mean number of pups born to females in the sample is less than ?⎯⎯⎯.

1. Commute times in the U.S. are heavily skewed to the right. We select a random sample of 240 people from the 2000 U.S. Census who reported a non-zero commute time. In this sample the mean commute time is 28.9 minutes with a standard deviation of 19.0 minutes. Can we conclude from this data that the mean commute time in the U.S. is less than half an hour? Conduct a hypothesis test at the 5% level of significance. What is the p -value for this hypothesis test?

2.A medical researcher is studying the effects of a drug on blood pressure. Subjects in the study have their blood pressure taken at the beginning of the study. After being on the medication for 4 weeks, their blood pressure is taken again. The change in blood pressure is recorded and used in doing the hypothesis test. Change: Final Blood Pressure - Initial Blood Pressure The researcher wants to know if there is evidence that the drug increases blood pressure. At the end of 4 weeks, 34 subjects in the study had an average change in blood pressure of 2.5 with a standard deviation of 5.1. Find the p -value for the hypothesis test.

3.Child Health and Development Studies (CHDS) has been collecting data about expectant mothers in Oakland, CA since 1959. One of the measurements taken by CHDS is the weight increase (in pounds) for expectant mothers in the second trimester. In a fictitious study, suppose that CHDS finds the average weight increase in the second trimester is 14 pounds. Suppose also that, in 2015, a random sample of 43 expectant mothers have mean weight increase of 16.2 pounds in the second trimester, with a standard deviation of 5.7 pounds. A hypothesis test is done to see if there is evidence that weight increase in the second trimester is greater than 14 pounds. Find the p -value for the hypothesis test.

Which hypothesis test you believe you should use and why.

• One Sample Proportion Z-test

• Two Sample Proportion Z-test

• One Mean t-test

• Pooled t-test

• Non-Pooled t-test

• Paired t-test

• ANOVA F-test

Questions:

4. The NOAA National Climatic Data Center of the United States provides data on the average annual temperature for every state in the United States. The average annual temperatures are based on data collected by weather stations throughout each state during the years 1971 to 2000. Is there strong evidence that the mean average annual temperature in the United States is greater than 50 degrees Fahrenheit? Explain. Use a significance level of 5%.

5. As gas prices continue to rise, more customers are beginning to take into account miles per gallon (a measure of the average distance traveled per unit of energy consumed) when determining which type of car to purchase. Do cars made in Japan typically get more miles per gallon than cars made in the United States? A random sample of 79 cars made in Japan had a mean of 30.48 and a standard deviation of 6.11 miles per gallon. A random sample of 249 cars made in the United States produced a mean of 20.14 and a standard deviation of 6.41 miles per gallon. Use a significance level of 0.10.

6. The U.S. Census Bureau reports that 26% of all U.S. businesses are owned by women. A Colorado consulting firm surveys a random sample of 410 businesses in the Denver area and finds that 115 of them have women owners. Should the firm conclude that its area is unusual? Test an appropriate hypothesis and state your conclusion. Use =0.05.

1. Review the following situations and determine the employee’s net pay by figuring out what earnings & benefits are subject to Income Tax, Canada / Quebec Pension Plan, Quebec Parental Insurance Plan (if applicable) and Employment insurance. Make sure to reduce net and taxable income by any applicable voluntary/non statutory deductions as well. All rates should be based on 2019.

1. Lawrence works in Alberta and is paid on a bi-weekly basis. He has a claim code of 1 on both his TD1 and TD1AB. He has the following type of earnings, benefits & deductions. He will not max out on CPP or EI this pay and will have full deductions.

1. Regular $2000
2. Vacation Pay $1000
3. Group Life – Employer paid Taxable benefit $25
4. RRSP contribution $150
5. Coffee Fund $5

Calculate Lawrence’s pensionable, insurable and taxable amounts. Then calculate CPP & EI deductions and look up the corresponding federal and provincial tax amounts in the tax tables based on his province, pay frequency and claim codes. Once all deductions have been calculated figure out the net pay.

2. Celine works in Nova Scotia and is paid on a semi-monthly basis. She has a claim code of 2 on both his TD1 and TD1NS. She has the following type of earnings, benefits & deductions. She will not max out on CPP or EI this pay and will have full deductions.

1. Regular $4000.00
2. Overtime $500.00
3. Parking – Employer paid Taxable benefit $50.00
4. RPP contribution $300.00
5. Union Dues $25.00

Calculate Celine’s pensionable, insurable and taxable amounts. Then calculate CPP & EI deductions and look up the corresponding federal and provincial tax amounts in the tax tables based on her province, pay frequency and claim codes. Once all deductions have been calculated figure out the net pay.

Leap year and Second in year program

1. Whether a year is a leap year on not a leap year.
2. The number of seconds in a year. (FYI, it will be a different amount for leap vs non-leap year.) You can calculate the seconds by whatever means you choose, whether with defined constants and calculations or just calculations. It is your choice.
3. If the user inputs a year number greater than zero, the program returns how many seconds were or will be in that year.
4. Put in descriptions for your request for input. If you do the bonus portion, also put that in for your request.
5. Tell the user that an input of -99 ends the program. (+5)
   Put your prompt in a loop, asking the user each time what year to check. (+5)
6. You should assume a day length of exactly 24 hours. Obviously, multiplying 365*24*3600 isn’t exactly a programming challenge, and it won’t even give the right answer for all years.
7. You must take account of leap years, which means your years will not all have the same number of days. If you do not already know, here is the calculation for leap years:

1. If a year is divisible by 4 with no remainder, it is a leap year,
2. unless it is a centurial year (ending in 00).
3. Then it is not a leap year,
4. unless it is a year divisible by 400, in which case it is still a leap year.

For example:

1904 is a leap year—evenly divisible by 4.
1900 is not a leap year—it is evenly divisible by 4, and also evenly divisible by 100. However, it is not evenly divisible by 400.
2000 is a leap year— it is evenly divisible by 4, evenly divisible by 100, but also evenly divisible by 400.
Your calculation should ignore all other variations in the length of the calendar year, such as leap seconds or the change from the Julian to the Gregorian system.

Exercise 19-08

Express Delivery is a rapidly growing delivery service. Last year, 80% of its revenue came from the delivery of mailing “pouches” and small, standardized delivery boxes (which provides a 20% contribution margin). The other 20% of its revenue came from delivering non-standardized boxes (which provides a 70% contribution margin). With the rapid growth of Internet retail sales, Express believes that there are great opportunities for growth in the delivery of non-standardized boxes. The company has fixed costs of $13,640,100.

(a) What is the company’s break-even point in total sales dollars? At the break-even point, how much of the company’s sales are provided by each type of service? (Use Weighted-Average Contribution Margin Ratio rounded to 2 decimal places e.g. 0.22 and round final answers to 0 decimal places, e.g. 2,510.)

(b) The company’s management would like to hold its fixed costs constant but shift its sales mix so that 60% of its revenue comes from the delivery of non-standardized boxes and the remainder from pouches and small boxes. If this were to occur, what would be the company’s break-even sales, and what amount of sales would be provided by each service type? (Use Weighted-Average Contribution Margin Ratio rounded to 2 decimal places e.g. 0.22 and round final answers to 0 decimal places, e.g. 2,510.)
