4-59. In building electronic circuitry, the breakdown volt-age of diodes is an important quality characteristic. The break-down voltage of 12 diodes was recorded as follows: 9.099,9.174, 9.327, 9.377, 8.471, 9.575, 9.514, 8.928, 8.800, 8.920,9.913, and 8.306.(a) Check the normality assumption for the data.(b) Test the claim that the mean breakdown voltage is lessthan 9 volts with a significance level of 0.05.(c) Construct a 95% one-sided upper confidence bound onthe mean breakdown voltage. (d) Use the bound found in part (c) to test the hypothesis.(e) Suppose that the true breakdown voltage is 8.8 volts; it isimportant to detect this with a probability of at least 0.95.Using the sample standard deviation to estimate the popu-lation standard deviation and a significance level of 0.05,determine the necessary sample size.

a)- To check the normality assumption, we can create a histogram and a normal probability plot: Here…
