Question

The population mean, according to a report is 20.4 minutes. To corroborate this, a sample of 15 data is taken.

19.86 19.47 19.12 20.33 20.71
20.48 19.36 20.15 20.43 20.56
19.19 20.59 19.78 20.80 19.56

Prepare a hypothesis test, with a significance level of 0.05, to investigate if the population mean is different from 20.4 minutes.

 

A p-value 0.02580 value of the test statistic: -2.4933 NO Rejection H0

B p-value 0.02580 value of the test statistic: 2.4933 NO Rejection H0

C p-value 0.02580 value of the test statistic: -2.4933 Rejection H0

D p-value 0.02580 value of the test statistic: 2.4933 Rejection H0
