One of the most popular products sold by a manufacturer of electrical fuses is the standard 30-ampere fuse used by electrical contractors in the construction industry. The company has tested a simple random sample of 16 fuses from its production output and found the amperages at which they €œblew€ to be as shown here. Given this information, and assuming the data are from a normally distributed population, construct and interpret the 95% confidence interval for the population mean amperage these fuses will withstand.
