SOLUTION: suppose you are using a=0.05 to test the claim that mu>14 using a p-value. you are given the sample statistics n=50 xbar=14.3 and s=1.2. find the p-value

suppose you are using a=0.05 to test the claim that mu>14 using a p-value. you are given the sample statistics n=50 xbar=14.3 and s=1.2. find the p-value
--------
Ho: u <= 14
Ha: u > 14 (claim)
-------
z(14.3) = (14.3-14)/[1.2/sqrt(50)] = 1.7678
---------------------
p-value = P(z > 1.7678) = normalcdf(1.7678,100) = 0.0385
