The article "supply voltage quality in low-voltage industrial networks of estonia" (t. vinnal, k. janson, et al., estonian journal of engineering, 2012: 102126) presents voltage measurements for a sample of 66 industrial networks in estonia. assume the rated voltage for these networks is 232 v. the sample mean voltage was 231.7 v with a standard deviation of 2.19 v. let μ represent the population mean voltage for these networks.
a. find the p-value for testing h0: μ = 232 versus h1: μ = 232.
b. either the mean voltage is not equal to 232, or the sample is in the most extreme% of its distribution.

Cor d? ? me ? max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
