A researcher is interested in estimating the mean weight of a semi tracker truck to determine the potential load capacity. She t
akes a random sample of 17 trucks and computes a sample mean of 20,000 pounds with sample standard deviation of 1,500. The 95% confidence interval for the population mean weight of a semi tracker truck is____________.
