For this hypothesis test, information about the sample and a standard error from a randomization distribution are provided.
H0: the mean = 26
Ha: the mean not = 26
n = 75, x bar = 25.5, s = 5.4 and the Standard Error estimated to be 0.6 (So .6 is an estimate for the standard deviation in the x bar distribution)
Find the value of the standardized z-test statistic.
Group of answer choices
a.) 0.278
b.) -1.5
c.) -0.833
d.) 2.5
