Sue , a researcher, is interested in estimating the mean weight of a semi tracker truck to determine the potential load capacity. She takes a random sample of 14 trucks and computes a sample mean of 25,000 pounds with sample standard deviation of 1,500. The 95% confidence interval for the population mean weight of a semi tracker truck is O 3186.912 > > 2705.132 O 3365.926 > M > 1634.074 3579.924 > > 1803.076 O 3579.924 > u > 1803.984 O Or none of the other choices
