The time needed for college students to complete a certain paper and pencil maze follows a Normal distribution with a mean of 80 seconds and a standard deviation of 15 seconds. You wish to see if the mean time μ is changed by meditation, so you have a group of 10 college students meditate for 30 minutes and then complete the maze. It takes them an average of = 75 seconds to complete the maze. Use this information to test the hypotheses

The time needed for college students to complete a certain paper and pencil maze follows a Normal distribution with a mean of 80 seconds and a standard deviation of 15 seconds. You wish to see if the mean time μ is changed by meditation, so you have a group of 10 college students meditate for 30 minutes and then complete the maze. It takes them an average of  = 75 seconds to complete the maze. Use this information to test the hypotheses
H0: μ = 80, Ha: μ 80

at significance level α = 0.02. What is your conclusion? State your evidence.
