A researcher wishes to see if the mean number of days that a basic, low-price, small automobile sits on a dealer's lot differs from 29. A sample of 27 automobile dealers has a mean of 30.5 days for basic, low-price, small automobiles. At = 0.05, test the claim that the mean time is greater than 29 days.The standard deviation of the population is 3.8 days

A) Multiple choice: Find the Null and alternative hypothesis,. Choose the correct answer

a) Claim: H₀: = 29 ; opposite H₁ : 29

b) Claim: H₀: 29 ; opposite H₁: = 29

c) Claim H_{1 :} 29 : opposite H₀: = 29

d) Claim H_1: = 29 opposite H₀: 29

Answer =

B) Find the test statistic: z =

C) Multiple choice: Find the P-value for the hypothesis test and decide whether to reject H₀ or not. a) 0.0201; fail to reject H₀

b) 0.0404; fail to reject H₀

c) 0.0201; reject H₀

d) 0.0404; reject H₀

Answer =

D) Multiple choice: Find the Critical value(s) =

a) 1.645 b) 1.96 c) 1.645 d) 1.96

E) Multiple Choice . Write the conclusion about the claim: Answer
