AMA Controls makes a switch that is advertised to activate a warning light if the power supplied to a machine reaches 100 volts. A random sample of 210 switches is tested and the mean voltage at which the warning light occurs is 96 volts with a sample standard deviation of 23 volts. Assume the population is normally distributed and use the confidence interval approach to test the hypothesis that the mean voltage activation is different from AAA Controls claim at the 0.10 significance level. Step 1 of 2: Calculate a confidence interval for the mean voltage at which the warning light occurs. Round your answers to two decimal places
