In a random sample of 26 laptop computers, the mean repair cost was $150 with a standard deviation of $35. Assume the
population has a normal distribution. Construct a 95% confidence interval for the population mean, p. Suppose you did some
research on repair costs for laptop computers and found that the standard deviation is e- 35. Use the normal distribution to
construct a 95% confidence interval for the population mean, p. Cormpare the results, Round to the nearest cent.
