Answer:
t value is 1.495
Explanation:
The null and alternative hypothesis are :
H0 : mu = 1327
ha: mu > 1327
This is a one tailed test
Critical value = 1.771
at 0.05 significance level with df = 14-1 = 13
test statistics:
s = 411.53, n = 14
t = (xbar -mu)/(s/sqrt9n))
= ( 1491.43 - 1327)/(411.53/sqrt(14))
= 1.495
Decision:
Reject H0 if tstat > 1.771
Fail to reject H0
