Question: A random sample of size n = 2 0 was drawn from a population of size N = 3 0 0 . The measurements shown

A random sample of size n=20 was drawn from a population of size N=300. The measurements
shown in the table to the right were obtained.
a. Estimate with an approximate 95% confidence interval in the form x+-2hat()x.
b. Estimate p, the proportion of measurements in the population that are greater than 30, with an
approximate 95% confidence interval in the form hat(p)+-2hat()hat(p).
a. An approximate 95% confidence interval estimate for is
(Round to three decimal places as needed.)
