Hypothesis Test

 

Consider the information above and in question 1. It is conjectured that the mean number of people attending all 2017 Veterans Day celebrations is 145, and of interest is to test this conjecture versus the alternative that the mean number of people attending all 2017 Veterans Day celebrations is different from 145 people

 

To test the hypothesis, a simple random sample of 41 Veterans Day celebrations was selected and the number of people attending each was recorded. The mean number of people attending for this sample of 41 celebrations was 157, with a standard deviation of 23 people. The distribution of the data was bimodal. If appropriate, use this information to test the hypotheses stated in question 3 at the a = .05 level of significance.

 

Is the population standard deviation known?

a) Yes

b) No

 

Based on the p-value and using a significance level α = 0.05, which of the following is the correct decision?

Based on the p-value and using a significance level α = 0.05, which of the following is the correct decision?

a) Reject the null hypothesis

b) Fail to reject the hypothesis

c) Accept the null hypothesis

d) Reject the alternate hypothesis

 

Based on the decision in #8, which of the following is the correct conclusion.

a)  There is insufficient evidence that the proportion of people attending all 2017 Veterans Day celebrations is different from 145 people.

b)  There is sufficient evidence that the mean number of people attending all 2017 Veterans Day celebrations is different from 157 people.

c) There is insufficient evidence that the mean number of people attending all 2017 Veterans Day celebrations is different from 157 people.

  d) There is insufficient evidence that the mean number of people attending all 2017 Veterans Day celebrations is different from 145 people.

e) There is sufficient evidence that the mean number of people attending all 2017 Veterans Day celebrations is different from 145 people.
