Solution :
= 34
=35.9
S =11.8
n = 84
This is the two tailed test .
The null and alternative hypothesis is ,
H0 : = 34
Ha : 34
Test statistic = t
= ( - ) / S / n
= (35.9-34) / 11.8 / 84
= 1.476
Test statistic = t = 1.476
P-value =0.1438
= 0.04
P-value >
0.1438 >0.01
Fail to reject the null hypothesis .
