- QUESTION 15 Prior to a set of compensation policy changes at a company 31% of the employees surveyed said that they liked their job very much, 45% said that they liked their job moderately, and the remaining employees said that they were dissatisfied with their job. Now, in a survey of 202 employees, 76 said they liked their job very much, 106 said that they liked their job moderately, and the remaining employees said that they were dissatisfied with their job. When testing (at the 5% level of significance) whether the proportions have changed, what is the critical value? (please round your answer to 3 decimal places)arrow_forwardQUESTION 14 Prior to a set of compensation policy changes at a company 31% of the employees surveyed said that they liked their job very much, 48% said that they liked their job moderately, and the remaining employees said that they were dissatisfied with their job.

- QUESTION 3 Historically, 76% of University of Arkansas faculty members purchase a parking pass every year. Donna Jean, the manager of parking facilities, believes that an increase in the price of parking passes will result in a decrease in the proportion of faculty members who will purchase parking passes. To test this idea, Donna Jean randomly sampled 400 U of A faculty members and asked them if they would buy a parking pass following the implementation of a price increase. Results indicate that 296 of the faculty members in her sample would purchase the more expensive parking passes, while 104 would not. Which of the following is the proper set of hypotheses? a. Ho: m.76; H1: m.76. Ob. Ho: ms.76; H1: m>.76 Oc. Ho: ma 76, H1: m<.76 Od.

Records were maintained that indicated the demand for dessert during the same time period. The owner decided to study two other variables, along with whether a dessert was ordered: the gender of the individual and whether a beef entrée was ordered. The results are as follows: A waiter approaches a table to make an order. What is the probability that the first customer to order at the table Orders a dessert? Order a dessert or a beef entrée? Is a female and does not order a dessert? Is a female or does not order a dessert? Suppose the first person that the waiter takes the dessert order from is a female. What is the probability that she does not order dessert? Are gender and ordering dessert independent? Is ordering a beef entrée independent of whether the person orders dessert?arrow_forward

A researcher wants to study the effect of a price change on the sales of various brands of a certain product. Assume the market is made up of four brands - W, X, Y and Z- and the price change (decrease) for brand W is introduced immediately after time t0. Assume every respondent buys exactly one unit of the product in each period. Data on number of respondents buying each brand in each period, based on a panel, are as follows: Y W 175 25 100 25 25 Y 25 50 50 25 Note: Confine your attention only to the data presented Assume the world starts at to and stops after ti and the strategies of brands X, Y, and Z are unchanged between to and ti. c) Which brand(s) other than W exhibited the highest loyalty rate? Show your calculations. d) Which of the brands X Y, Z should be most worried about W's promotion? Show your calculations. toarrow_forward
