a Consider a paint-drying situation in which drying time for a test specimen is normally distributed with or -7. The hypotheses HQ - 74 and H, < 74 are to be tested using a random sample of 25 observations (a) How many standard deviations of below the null value is * = 72.37 (Round your answer to two decimal places.) standard deviations (b)x - 72.3, what is the conclusion using - 0.0057 Calculate the best statistic and determine the P-value. (Round your test statistic to two decimal places and your p-value to four decimal places.) 2- P-value State the conclusion in the problem context. Reject the nult hypothesis. There is sufficient evidence to conclude that the mean drying time is less than 74 Do not reject the null hypothesis. There is sufficient evidence to conclude that the mean drying time is less than 74 Reject the null hypothesis. There is not sufficient evidence to conclude that the mean drying time is less than 4 Do not reject the nut hypothesis. There is not sufficient evidence to conclude that the mean drying time is less than 24 (c) For the test procedure with 0.005, what is 70)? (Round your answer to four decimal places) (70) - (d) If the test procedure with a 0.005 is used, what is necessary to ensure that M70) = 0.012 (Round your answer up to the next whole number) - specimens (e) If a level 0.01 test is used with n=100, what is the probability of a type 1 error when = 76? (Round your answer to four decimal places.)
