Chapter 8 Reflection:

The National Center for Education Statistics reported that 47% of college students work to pay for tuition and living expenses. Assume that a sample of 450 colleges students was used in this study.

1. Provide a 95% confidence interval for the population proportion of college students who work to pay for tuition and living expenses.

2. Provide a 99% confidence interval for the population proportion of college students who work to pay for tuition and living expenses.
3. What happens to the margin of error as the confidence is increased from 95% to 99%? Explain why this makes sense.

4. Suppose the NCES would like to re-do their study. If they want a 95% confidence interval with a margin of error for the population proportion within ±0.03, determine the sample size they should use. Use p*=0.47, the sample proportion from their previous study.

Question 5 [Note this question is from the Week 9 Tutorial] a) In Chapter 9 (Week 9 Tutorial) we discussed the integration of the Human Resource Management and Payroll databases. In particular, we discussed different benefits of this integration in the Week 9 Tutorials. Some companies believe in the integration of HRM and Payroll systems. However, many firms do not agree with this integration. These companies maintain separate HRM information systems and Payroll. Required: Discuss both arguments. For this discussion, think in terms of (1) difference in employee background, and (2) functions performed by the HRM and payroll departments. [7 marks] [7 marks. Word limit: Up to 250 words.] b) Mr Peter is the treasurer of a small charity and you asked him to explain the business activities and data processing operations involved in the payroll cycle of the charity. During this discussion, Peter explained that the charity is not using a separate cheque account to manage their Payroll due to the extra monthly services fee. Peter further explained that the benefits of a separate cheque account are not worth the additional fee. Required: As a student of accounting information systems, how would you respond to Peter?

1. Write a program that keeps asking the user for a password until they correctly name it. Once they correctly enter the password, the program congratulates the user and tells them how many guesses it took. Be sure to be grammatically correct with the guess/guesses output. Call the program LastNamePassword. Example (user input in italics) What is the password? monkeys Incorrect. Guess again. dishwasher Incorrect. Guess again. aardvark Correct! You got the password, and it took you 3 guesses to get it correct. 2. Write a program that takes a string input from the user and then outputs the first character, then the first two, then the first three, etc until it prints the entire word. After going up to the full word, go back down to a single letter. LastNameUpDown. Input: Kean Output: K Ke Kea Kean Kea Ke K 3. Write a program where the user enters a string, and the program outputs a string where for every char in the original, there are two chars except if the character is the number 2. If that happens, do not duplicate the 2. Call your program LastNameDoubles. Input Output The → TThhee AAbb → AAAAbbbb Hi-There → HHii—Tthheerree 1234 → 1123344

In this​ example, mu Subscript d is the mean value of the differences d for the population of all pairs of​ data, where each individual difference d is defined as the words spoken by the male minus words spoken by the female.

QUESTION 1:

Researchers claim that women speak significantly more words per day than men. One estimate is that a woman uses about 20,000 words per day while a man uses about 7,000. To investigate such claims, one study used a special device to record the conversations of male and female university students over a four- day period. From these recordings, the daily word count of the 20 men in the study was determined. Here are their daily word counts:

What value we should remove from observation for applying t procedures?

A 90% confidence interval (±±10) for the mean number of words per day of men at this university is from  to  words.

Is there evidence at the 10% level that the mean number of words per day of men at this university differs from 7000?

QUESTION 2:

You are testing H₀: µ = 100 against H_a: µ < 100 based on an SRS of 16 observations from a Normal population. The data give x¯¯¯x¯ = 9.5 and s = 5.9.

The value of the t statistic (±0.01) is  

When people smoke, the nicotine they absorb is converted to cotinine, which can be measured. A sample of 60 smokers has a mean cotinine level of 172.5 ng/ml. Assuming the σ is known to be 99.5 ng/ml, test the claim that the mean cotinine level of all smokers is equal to 200.0 ng/ml. Use a 0.05 significance level.

1.   Copy and paste the Minitab output for exercise into the document underneath the problem.   You are not also required to do these by hand, unless you want to.  

2. Write the rejection rule word for word as written here, "Reject Ho if the p-value is less than or equal to alpha."

3.   Write the actual p-value and alpha, then either "Reject Ho" or "Do not reject Ho." As an example: 0.0021 ≤ 0.05. True. Reject Ho.

4.    Write an English sentence stating the conclusion, claim, and significance level. As an example: If the claim is "Can we conclude that male business executives are taller, on the average, than the general male population at the  α  = 0.05 level?", and if we found our conclusion to be do not reject Ho, the sentence would be, "There is not enough evidence to conclude that  male business executives are taller, on the average, than the general male population at the  α  = 0.05 level."
