HW 9.5 Score: 0/38 0/22 answered Question 16 Test the claim that the proportion of days that temperature (in degrees F) in Santa Maria exceeds 74 degrees is different than 0.35. A random sample of 90 days yields 22 days in which the temperature exceeds 74 degrees. Use a = 0.01. 1. The sample size restriction for this test is: O Need at least 5 successes and 5 failures None needed since population is normally distributed O Need n > 30 The hypotheses are: O Ho:p 2 0.35; Ha:p 0.35 O Ho:M 0.35 O Ho: u 2 0.35; Ha:M or '3' Reject Ho since P :3 o: '33:? Do not reject Ho since P 3' or '33:? Reject Ho since P g o: The conclusion is: '3' There is insufficient evidence to conclude that the proportion of days temperature in Santa Maria exceeds 74 is not different than 0.35 '13:} There is sufficient to conclude that the proportion of days temperature in Santa Maria exceeds 74 is not different than 0.35 '3' There is insufficient evidence to conclude that the proportion of days temperature in Santa Maria exceeds 74 is different than 0.35 '33:? There is sufficient evidence to conclude that the proportion of days the temperature in Santa Maria exceeds 74 is different than 0.35 Question 17 61 59 66 63 57 59 64 61 67 62 58 63 67 Test the claim that a population mean score on an exam is more than 60 based on the exam data in the table above. Use a = 0.05. 1. The population distribution requirement for this test is: O None since this is a Z-test O Need a normally distributed population since this is a T-test O Need a normally distributed population since n 60 O Ho:p = 60; Ha:p # 60 O Ho:p 2 60; Ha:p 60 O Ho:u = 60; Ha: u # 60 2. This is a O two right left tailed test and the distribution used is O T since o not known O Z since o known O Z since testing a proportionThe Degrees of Freedom are '31:? WA; this is a Z-test {:21- 13 {:21- 12 3. The STS (round to 3 decimals} is: The P-value (round to 4 decimals} is: 4. The decision at a: = 0.05 is: '33:? Reject Ho since P E a C' Do not reject Ho since P > a: '33:? Reject Ho since P :3 a '33:? Do not reject Ho since P 3' or The conclusion is: '33:? There is sufficient evidence to support the claim that the population mean score is more than 60 '3' There is insufficient evidence to reject the claim that the population mean score is more than 60 '33:} There is insufficient evidence to support the claim that the population mean score is more than 60 '3' There is sufficient evidence to reject the claim that the popuation mean score is more than 60
