Question

The duration of an inspection task is recorded in seconds. It is claimed that

the inspection time is less than 100 seconds.

(a) Test this claim at 0.05 significance level.

(b) Calculate the corresponding p-value and comment

Answer 1

If the null hypothesis is the claim that the inspection time is less than 100 seconds, the test result (one-sample t-test) fails to reject the null (one-sided p=0.274).
