Since many people have trouble programming their DVD players, an electronics company has developed what it hopes will be easier instructions. The goal is to have at least 95% of customers succeed at being able to program DVD players. The company tests the new system on 100 people, 92 of whom were successful. Is this strong evidence that the new system fails to meet the company's goal? A student's test of this hypothesis is provided. How mistakes can you find? i Click the icon to view the student's test of the hypothesis. Identify any mistakes in the student's calculation of the P-value. If there are any mistakes, show what the correct calculations for the P-value should be. Choose the correct answer below. O A. The student's calculation of SD (p) is incorrect and carries through the calculation ofthe P-value, SD (p) (0.92)(0.08) 0.92 - 0.95 100 = 0.0271, Z= 0.0271 -1.11; P=P(Z - 1.36) = 0.91 O D. The calculation of the probability is incorrect; P = P(z> - 1.36) = 0.09 Identify any mistakes in the student's conclusion. If there are any mistakes, state what the correct conclusion should be Assume all requirements for the test are satisfied. Choose the correct answer below. O A. There is strong evidence that the new system works O B. The student's conclusion is correct. O C. There is no evidence that the new system works. O D. There is strong evidence that the new system does not work Click to select your answer. 5:52 PMSince many people have trouble programming their DVD players, an electronics company has developed what it hopes will be easier instructions.

Ho p= 0.95, HA: P 0.92 Identify any mistakes in the student's verification of assumptions and conditions. If there are any mistakes, state what the correct verification of assumptions and conditions should be. Choose the correct answer below. O A. The student's verification of assumptions and conditions is correct O B. Unnecessary information is given; SRS (Simple Random Sample) O C. The calculation of nq is incorrect and the 10% condition is missing, SRS (Simple Random Sample), 0.95(100) > 10, 0.05(100)
