Construct a 90% confidence interval for the mean weight of this company’s golf balls. Assume normality. (0.70881, 2.5194) (1.6107, 1.6175) (0.85436, 2.3738) (1.6116, 1.6166) (1.6113, 1.6168)
The USGA requires that golf balls have a weight that is less than 1.62 ounces. An engineer for the USGA wants to verify that a company’s golf balls conform to USGA standards. A random sample of 12 golf balls from this company is obtained and the weights are given below.
1.614 1.614 1.621 1.621 1.619 1.610 1.612 1.602 1.614 1.610 1.615 1.617
