A) does not exceed; p < .01
B) does not exceed; p < .05

D) exceeds; p > .05
Z-statistic
A specific kind of norm score that shows the number of standard deviations by which an individual item deviates from the distribution's average.
Critical Value
The threshold in a statistical test that defines the boundary for rejecting the null hypothesis.
Calculated Value
A numerical value derived from a mathematical computation or formula.

Final Answer :
C
Explanation :
If the calculated value of a z-statistic does not exceed the critical value, it means that the difference between the sample mean and the population mean is not statistically significant at the 0.05 level (p > .05). This means that we fail to reject the null hypothesis, which states that there is no significant difference between the population mean and the sample mean.
