Expert Answer

Step 1

In this question, we have the data for two groups and we have to find the inference about  the population based on the given data set.

Step 2

We have done some calculations based on the given data to make the inferences about the population.

d.) Based on the above calculations

  • Since the Test Statistical Value (0.61), does not lies within critical region,
  • Therefore, we do not have enough evidence to reject the null hypothesis,
  • So, the claim made by researcher is true.
  • Therefore, we conclude that mean recall time for Audiovisual presentation and only visual representation is same.

Step 3

e.)

Since the P Value is 0.542 which is greater than level of significance 0.10, Which shows that we do not have enough evidence to reject the null.

Therefore, the claims seem to be true which means mean ...
