A rаndоm sаmpling оf 40 DSU full-time fаculty salaries indicates an average salary оf $65,000 with a sample variance of $91,000. Data for all Utah university faculty suggests a variance (Sigma^2) of $94,000. Answer the following questions to test DSU administration's claim that the variance in full-time faculty salaries at DSU is the same or more than that for Utah institutions of higher education in general (alpha=0.10).H0: sigma^2 [c1] 94,000 (enter correct sign(s))H1: sigma^2 [c2] 94,000 (enter correct sign(s))The claim is an [m1] (enter H0 or H1)The critical value on the left, if there is one = [cv1] (round to 2 decimals-if none, enter "na")The critical value on the right, if there is one = [cv2] (round to 2 decimals-if none, enter "na")The test statistic = [ts] (round to 2 decimals)The result of the hypothesis test of H0 is [result] (enter "reject H0" or "fail to reject H0")Is the claim supported? [support] (enter yes or no)
Fоr eаch оf the fоllowing scenаrios, stаte the claim and whether or not it is supported. A. A researcher claims that men, on average, can't wait even 5.0 seconds without pressing a button on the tv remote control (i.e., average time between remote control use). Assuming that a hypothesis test has been conducted and that the conclusion is to reject the null hypothesis, answer the following questions. The claim is an [claim1] (enter H0 or H1) and is mu [symbols1] 5.0 seconds (enter correct sign(s)) Is the claim supported? [support1] (enter yes or no) B. A cereal company claims that the proportion of cereal boxes that meet its weight specification is at least 95%. Assuming that a hypothesis test has been conducted and the conclusion is, fail to reject the null hypothesis, answer the following questions. The claim is an [claim2] (enter H0 or H1) and is p [symbols2] 95% (enter correct sign(s)) Is the claim supported? [support2] (enter yes or no) C. A manufacturer claims that the standard deviation in temperature in their refrigerators is no more than 2.2 degrees F. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, answer the following questions. The claim is an [claim3] (enter H0 or H1) and is sigma [symbols3] 2.2 degrees (enter correct sign(s)) Is the claim supported? [support3] (enter yes or no)
