Ex 9. Suppose that a national survey finds that 73 percent of restaurant employees say that work stress has a negative impact on their personal lives. A random sample of 200 employees of a large restaurant chain finds that 141 employees say that work stress has a negative impact on their personal lives. a. Formulate the null and alternative hypotheses needed to attempt to provide evidence that the percentage of work-stressed employees for the restaurant chain differs from the national percentage. b. Use critical values to perform the hypothesis test by setting α equal to .10, .05, .01, and .001

Fail to reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually different from 0.32. C.

The effectiveness of a new bug repellent is tested on 14 subjects for a 10 hour period. (Assume normally distributed population.) Based on the number and location of the bug bites, the percentage of surface area exposed protected from bites was calculated for each of the subjects. The results were as follows: x¯=93, ?=6 The new repellent is considered effective if it provides a percent repellency of at least 9090. Using ?=0.01, construct a hypothesis test with null hypothesis ?=90 and alternate hypothesis ?>90 to determine whether the mean repellency of the new bug repellent is greater than 9090 by computing the following: (a) the degrees of freedom (b) the test statistic
A p-value of 0.02 means that you must: a. Reject the null hypothesis b. Accept the null hypothesis c. Go back to the drawing board because you shouldn’t get a result higher than 0.05 d. Recode your data so you make sure to get statistically significant results
College students listened to either Mozart or silence, and then took an IQ test. Researchers hypothesize that, on average, students perform better on the IQ test after listening to Mozart than after listening to silence. a) Define the parameter of interest both in words and using the appropriate statistical symbol. b) State the null and alternative hypotheses. c) If the p-value of the test is 0.678, can we conclude that there is no difference in IQ scores after listening to Mozart and after listening to silence, on average, in the population of college students? Explain
