Question 633911: A researcher claims that the average age of people who buy lottery tickets is 64. A sample of 30 is selected and their ages are recorded as shown below. The standard deviation is 9. At a
= 0.05 is there enough evidence to reject the researcher’s claim? Show all work.
You can put this solution on YOUR website! Null Hypothesis: µ = 64 (Claim)
Alternative Hypothesis: µ ≠ 64
t Test, df = 29
Test Statistic, t: -0.5338
Critical t: ±2.0452
P-Value: 0.5976
Fail to Reject the Null Hypothesis
Sample does not provide enough evidence to reject the claim that the average age of people who buy lottery tickets is 64.
