Question 1172027
Ho: time is 6
Ha: time is not 6
alpha can be set for 0.05, although other values could be used p{reject Ho|Ho true}
test statistic is a t (0.975, df=15)
critical value is |t| > 2.131
t=(x bar-mean)/s/sqrt(n)
=-1*sqrt(16)/2.3
=-1.74, the absolute value of which is not > 2.131
Fail to reject Ho at the 5% level; insufficient evidence to show that the true value is not 6 hours.
p-value= 0.10
