I would like to know if the sex of a math student is a statistically significant factor in predicting average math exam scores. The following lists are exam scores for a math exam, separated by sex.

male 89 33 104 48 90 80 98 32 98 55 75 74 73 90 105 47 48 67 99 103 63

female 99 80 81 88 94 83 70 42 78 75

Perform a hypothesis test to determine whether the sex of a math student is statistically significant for performance on math tests. In other words, is there a statistically significant difference between the scores of these two groups of students?

(a) State the null and alternative hypotheses. Also, state the meaning of your parameters.

(b) Perform the test. Use α = .05. Show your work. Clearly indicate the value of the test statistic. Be sure to mention the value of df if it is relevant. Also, make sure you clearly state your final answer to the question above.

(c) Compute an appropriate 95% confidence interval that would confirm your final answer from part (b). Explain why it confirms that answer.

Practice problems 1 – Type of variables
1. In the following situations give an example of a parameter and a statistic

a. Political elections
b. Subaru 2020 Forester vehicles c. RUM students
d. Puerto Ricans

2. You are in charge of a local company who wants to obtain mean income of the company’s engineers to compare with the mean income of engineers in the industry. You can either obtain the population mean (parameter) or a sample mean (statistic) to reach a managerial conclusion (both describing the same property, and assume both are feasibly possible to get). Which one would you rather use? Explain

3. Determine the type of variable in the following problems (Nominal, ordinal, quantitative). If quantitative state if it is discrete or continuous

a. Times power outages occur in Mayaguez Terrace last December b. Level of attraction of a person (de feo(a) a guapísimo(a))
c. Volume of chocolate by 25 kids sampled in October.
d. Sustained winds of hurricane Irene in the last 24 hours.

e. Placing at a marathon
f. Cell phone ownership (Yes, No) by citizens who are 50 or older

5. Of the examples above mention one that describes a parameter and one that describes a statistic.

Firstly, I wasn't sure exactly where to put this. It's a typesetting query but the scope is greater than TEX; however it's specific also to physics and even more specific to this site.

I've recently been reading a style guide for scientific publications (based on ISO 31-11), however there was no mention of quantum mechanical operators. I've seen them written a few ways and was wondering if there was a decision handed down from "up above" that any particular way is best.

H -- I see this most commonly but I suspect it's mostly due to (mild) laziness to not distinguish it from a variable.
H^ -- This is nicer to me because it makes the distinction between operator and variable. From what I understand of the ISO the italic means it's subject to change, which is true of the form of an operator, but not really its meaning? So I'm not totally sure if that's appropriate here.
H -- Roman lettering is used for functions e.g. sinx, erf(x), and even the differential operator (as in ddx) so this seems to me like the most suitable category to put operators in.
H^ -- Probably the least ambiguous but may also be redundant.

Which would be the best to use? Am I being too pedantic?

Assignment: Prepare the Cash Flow Proforma for 5 years based on

the above assumptions and Proforma Results of Operations posted on

Angel. What is the ending Cash balance?

If you deposit $500 from year 1 to year 5, $300 from year 6 to year 20, no deposits year 21 and year 22, and $700 in year 22. If the discount rate is 5%, what is the present value? Please show all steps

Visby Rides, a livery car company, is considering buying some new luxury cars. After extensive research, they come up with the above estimates of free cash flow from this project. By how much could the discount rate rise before the net present value (NPV) of this project is zero, given that it is currently 10%?

ou are given the following stream of cash flows: Year 1 Year 2 Year 3 Year 4 Year 5 $100,000 $110,000 $120,000 $130,000 $140,000 A. If you thought the appropriate discount rate was 10%, what would be the present value of this cash flow stream today at t=0? B. If you thought the appropriate interest/discount rate was 10%, what would be the future value of this cash flow stream in five years at t=5 years?

Assignment: Finance and Operations This week we look at finance and operations, and apply a bit of quantitative analysis to the effort. Your assignment is to analyze current financial ratios for a given business. 1. Think of a specific business you find interesting, i.e. Apple, UTC, Southwest Airlines, etc. 2. Search the web for that business’ “Financial Statement.” (You will find many hits for the data.) 3. Select the http://www.morningstar.com/ site offering your company’s financial statement. 4. You will now see a number of financial ratios for your company. Below is an example for Apple: http://financials.morningstar.com/ratios/r.html?t=AAPL 5. Now, define the following ratios, note the ratio for your business, and explain what the ratio means for the business moving forward: a) Return on Assets b) Return on Equity c) Return on Capital d) Gross Margin e) SG&A Margin f) Current Ratio g) Quick Ratio h) Total Debt/Equity i) Total Revenue j) Gross Profit Here are some additional resources: Apple (Return on Assets): https://ycharts.com/companies/AAPL/return_on_assets Ratios: https://www.stock-analysis-on.net/NASDAQ/Company/Apple-Inc/Ratios/Profitability/Quarterly-Data#Ratios-Summary Use the following guidelines: Use APA format with a title page, in-text citations and references.
