Quiz 5: Sections 8.1 - 8.3 You must show your work to obtain full credit. Points may be deducted if you do not justify your final answer. Total = 20 points. Identify the hypotheses, test statistic, P-value, and conclusion that addresses the original claim. 1) In a clinical study of an allergy drug, 108 of the 202 subjects reported experiencing significant relief from their symptoms. At the 0.01 significance level, test the claim that more than half of all those using the drug experience relief. 2) Various temperature measurements are recorded at different times for a particular city. The mean of 20C is obtained for 60 temperatures on 60 different days. Assuming that o = 1.5.C, test the claim that the population mean is 23.C. Use a 0.05 significance level.3) Test the claim that for the adult population of one town, the mean annual salary is given by p. = $30,000. Sample data are summarized as n = 17, x = $22,298, and s = $14,200. Use a signicance level of or = 0.05. 4) The time (in number of days) until maturity of a certain variety of hot pepper is Nonnally distributed, with mean u and standard deviation 0 = 2.4. This variety is advertised as taking 70 days to mature. I wish to test the hypotheses Ho: M = 70, H1: p > 70, so I select a simple randon sample of four plants of this variety and measure the time until maturity. The four times. in day are 76 73 69 70 Based on the data A) I would reject H0 at level 0.10 but not at level 005. B) I would reject Ho at level 0.05 but not at level 0.01. C) I would reject H0 at level 0.0l . D) None of the above
