Question

For each of the following Hypothesis Tests perform each of the following steps.

State the hypotheses and identify the claim.
Compute the test statistic
Find the P-value.
Make the decision.
Write the conclusion.

Assume all populations are normally distributed. Test all claims at 0.05.

A statistics class was given a pretest on probability (since many had previous experience in some other class). Then the class was given a six-page review handout to study for two days. At the next class, they were given another test. Is there sufficient evidence that the scores improve?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
