A university wants to determine whether a recently hired instructor (Instructor I) is working out. Nineteen (19) out of 30 of “Instructor I” students passed a certain test on the first try. In comparison, 57 out of 72 of more experienced “Instructor II” students passed the test on the first try. Use the appropriate test at α = 0.05 level of significance to answer the following question: Is the success rate of “Instructor II” greater than success rate of “Instructor I”? Yes, because the p-value is 0.047 No, because the p-value is 0.047 No, because the p-value is 0.102

Based on information from a previous study, r1 = 39 people out of a random sample of n1 = 105 adult Americans who did not attend college believe in extraterrestrials. However, out of a random sample of n2 = 105 adult Americans who did attend college, r2 = 50 claim that they believe in extraterrestrials. Does this indicate that the proportion of people who attended college and who believe in extraterrestrials is higher than the proportion who did not attend college? Use ? = 0.01.

The Norwegian government wants to know whether restricting the opening hours of liquor stores reduces alcohol consumption. Holger, an employee of Statistics Norway, is asked to investigate this research question. He uses panel data for n = 60 municipalities observed in T = 10 time periods. The data set contains information on per capita alcohol consumption (in liters per year) in municipality i in year t (alcoholit) and on the number of hours that liquor stores were open during year t in municipality i (hoursit). Holger estimates by OLS and obtains the following estimation results. regress alcohol Inhours, robust Linear regression alcohol alcoholit Bo + ßiln(hoursit) + Uit B Inhours cons Coef. 5.288235 2.768777 Robust Std.

An industrial-organizational psychologist believes that implementing a 2-hour lunch break at US companies will have an effect on employee productivity. On a productivity scale from 1 to 15, the average productivity score for all companies in the US is 8 (u = 8.00, ỡ = 4.00). The IO psychologist randomly samples 5 companies and has the companies implement a 2-hour lunch break for 1 month. At the end of the month, the lO psychologist measures the productivity scores for the five companies and obtains the following scores: 9, 14, 10, 12, 15 Using the appropriate hypothesis test and the six steps of hypothesis testing, determine what the 10 psychologist should conclude about the effect of a 2-hour lunch break on employee productivity. 1. What is the appropriate test to use ? 2. List the test's assumptions .You do NOT have to test the assumptions. 3. What are the null and alternative hypotheses ? 4. Construct a sampling distribution of means representing the null hypothesis. Specify the…

14% of all Americans suffer from sleep apnea. A researcher suspects that a higher percentage of those who live in the inner city have sleep apnea. Of the 391 people from the inner city surveyed, 59 of them suffered from sleep apnea. What can be concluded at the level of significance of αα = 0.05?
What proportions of males and females wear a facemask while in a large parking lot? There is some evidence that the proportion of females wearing facemasks, pf , is different from the proportion of males wearing face masks, pm . We are going to examine this question by randomly selecting n=900 males and m=800 females walking in parking lots and observing how many of the selected people are wearing masks. Let XM equal the number of males in our sample who wear masks. Let XF equal the number of females in our sample who wear masks. Suppose XM = 494 and XF = 494. Let pmhat be the sample proportion of males in our sample who wear masks. Let pfhat be the sample proportion of females in our sample who wear masks. Let pm be the (unknown) true proportion of males who wear masks in large parking lots. Let pf be the (unknown) true proportion of females who wear masks in large parking lots.a)Calculate an unbiased point estimate of pm . b) We wish to construct a 90 % classical confidence…
