Question 1181997
Ho: mu=83
Ha: mu NE 83
alpha=0.05 p{reject Ho|Ho true}
test is a t df=31
critical value at 0.05 |t| >2.04
at 0.1 |t| >1.70
calculation is t=(x bar-mean)/s/sqrt(n)= -2.5*sqrt(32)/10=-1.414
fail to reject Ho p-value is 0.167
Insufficient evidence at both values of 0.05 and 0.1 to reject Ho.
