Reference no: EM132464702

A simple random sample of 100 concert tickets was drawn from a normal population. The mean and standard deviation of the sample were $120 and $25, respectively. Test the hypothesis H0: µ = 125 vs. H1: µ ≠ 125 at the 1% significance level.

Rejection region: | t | > t0.05,99 = 1.66

Test statistic: t = -2.0

p-value one tail= 0.024

p-value two tail= 0.048

What is your conclusion?

Group of answer choices

Don't reject H0

Reject H0

We can infer that the population mean is not equal to $125

There is not enough information to draw a conclusion
