Practice Questions

Question 1

When using a standard normal distribution table, if you are looking for the probability of a Z-score being between two values, say $Z_1$ and $Z_2$ (where $Z_1 < Z_2$), how would you calculate this probability using the table's values?

Question 2

When using a t-distribution table, if you are performing a two-tailed test with a significance level of $\alpha$ and $df$ degrees of freedom, which column in the table should you typically look under?

Question 3

A researcher wants to find the critical value for a $98\%$ confidence interval using a standard normal distribution table. Which Z-score would they typically look for?

Question 4

When using statistical software to calculate a p-value for a hypothesis test, what does a very large p-value (e.g., $p > 0.10$) generally indicate?

Question 5

To find the Z-score corresponding to the $10^{th}$ percentile of a standard normal distribution using statistical software or a calculator's inverse normal function, what area value should be input?
