3. Mnemonic training has been suspected to improve ability to perform well on tests and, hence, test scores. The test results for 10 randomly selected students before and after participating in mnemonic training are as follows (note: higher scores indicate better performance on the test): 2 3 4 5 6 7 8 9 10 Student 423 342 480 46 Before 204 393 391 265 326 220 After 223 412 402 285 353 243 443 340 582 49 Does this sample of participants show sufficient evidence that mnemonic training improves test scores? Use the 5% level of significance and assume Normality of scores. a. (2 points) State the null and alternative hypotheses luales mortwy? Ho: H1 : b. (2 points) What calculator test will you use? List the requirements that must be met to use this test, and indicate whether the conditions are met in this problem. c. (2 points) Run the calculator test and obtain the P-value. d. (2 points) Based on your P-value, will you reject or fail to reject the null hypothesis? e. (2 points) Interpret your conclusion from part d in the context of this problem. 9
