Question

A survey taken several years ago found that the average time a person spent reading the local daily newspaper was 10.8 minutes. To see whether the average time had changed since the newspaper's format was revised, the newspaper editor surveyed 36 individuals. The average time that the 36 people spent reading the paper was 12.2 minutes. The standard deviation of the sample was 3 minutes.

(a) At α = 0.02, is there a change in the average time an individual spends reading the newspapers?

Test by using confidence interval for the mean. Round confidence interval to nearest thousandth.

Show step1-step3.

(b). Do the results agree? Explain why.

Steps for Hypothesis testing.
Step1)State null and Alternative Hypothesis.
Step2) Apply p-value and Classical(Traditional) Approach
Classical Approach: CV vs Test Statistic
p-value Approach: p-value vs Alpha (Level of Significance)
Step3)
State conclusion.
Claim is Alternative Hypothesis:
Reject Null Hypothesis: There is sufficient evidence to conclude that
Do not reject Null Hypothesis: There is insufficient evidence to conclude that
Claim is Null Hypothesis:
Reject Null Hypothesis: There is sufficient evidence to reject that
Do not reject Null Hypothesis: There is insufficient evidence to reject that
