Solution :
= 3
= 2.7
= 0.9
n = 81
This is the right tailed test .
The null and alternative hypothesis is ,
H0 : = 3
Ha : 3
Test statistic = z
= ( - ) / / n
= (2.7-3) / 0.9 / 81
= -3
Test statistic = z = -3
P(z > -3 ) = 1 - P(z < -3 ) = 1 - 0.0013
P-value =0.9987
= 0.01
P-value >
0.9987 > 0.01
Fail to reject the null hypothesis .
