To test H0÷μ=107 against H1÷μ107

 

Sample mean x=114

Sample standard deviation s=8.34

Sample size n = 9

 

The test statistic:

t=n(x-107)s 

 

which under H0 follows a t distribution with n-1 df.

 

Reject H0 at a 5% level of significance if tobs>t0.025

 

The value of the test statistic tobs=2.51799

and critical value t0.025,8=2.306

 

Since tobs=2.51799>t0.025,8=2.306 ,we reject H0 at 5% level of significance and we can conclude that the mean key performance indicator is significantly different from 107
