![A sample of 350 voters aged 18 to 25 were asked whether they thought Social
Security benefits should be increased for people over the age of 65. One-hundred forty-
seven of them answered yes. Based on this sample information, estimate the true
proportion of all 18 to 25 year olds who support an increase in Social Security benefits,
via a 99% confidence interval. Then, using @ =.01, perform a hypothesis test to
determine if less than 50% of all 18 to 25 year olds think Social Security benefits should
