If the value of a calculated z-statistic ______ the critical value, you would say ______.
A) exceeds; p > .05
B) exceeds; p < .05
C) does not exceed; p < .05
D) does not exceed; p < .01
Z-statistic
A statistic used in hypothesis testing, calculated as the difference between a sample statistic and its hypothesized population parameter, divided by the standard error.
Critical Value
A limit in hypothesis testing that establishes the criteria for dismissing the null hypothesis.
Calculated Value
A numerical value obtained through mathematical computations, often used in statistical tests to determine significance.

Final Answer :
B
Explanation :
When the value of a calculated z-statistic exceeds the critical value, it means that the obtained result is statistically significant at the alpha level of 0.05 (i.e., p < .05), meaning we can reject the null hypothesis. Therefore, the correct choice is B.
