Karen took bus number 14 during peak hours on 18 different deviation of 2.3 minutes. At the 0.01 significance level, test the claim that the mean waiting time is less than 10 minutes.

Explanation / Answer

Solution:

Ho:=10

Ha:<10

alpha=0.01

test statistic:

t=sample mean-population mean/sample sd/sqrt(n)

=7.6-10/2.3/sqrt(18)

=-4.42

Df=n-1=18-1=17

p=0.000187

p<0.05

Reject null hypothesis.

Accept alternative Hypothesis.

There is sufficient statisticla evidence at 5% level of signiifcance to conclude that the mean waiting time is less than 10 minutes
