Suppose you work for a company that manufactures electronics. The development analysts estimate that 5% of their flagship product will fail within 2 years of the purchase date, with a replacement cost of $ 1600.A newly hired associate at the company proposes to charge $ 73 for a 2 year warranty.a. Compute the expected value of this proposal. Let X be the amount profited or lost (by the company) on the warranties and P(X) is the probability.

Using traditional methods it takes 99 hours to receive an advanced driving license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 190 students and observed that they had a mean of 100 hours. Assume the population variance is known to be 49. Is there evidence at the 0.05 level that the technique lengthens the training time? Step 4 of 6 : Find the P-value of the test statistic. Round your answer to four decimal places.
