According to a Pew Research Center nationwide telephone survey of adults conducted March 15 to April 24, 2011, 69% of college graduates said that their college education gave them maturity (Time, May 30, 2011). Suppose that this survey included n=1390 college graduates. A. What is the point estimate of the corresponding population proportion?

A. The point estimate corresponding to the population proportion is 959 college graduates

Step-by-step explanation:

The given parameters are;

The percentage of the college graduates that said that college education gave them maturity, p' = 69%

The number of college graduates included in the study, n = 1,390

The point estimation is the process of using a sample data for the calculation of a single value

The point estimate of a population proportion, p', in a sample where there are 'x' number of success and the sample size is 'n', is given as follows;

p' = x/n

Therefore, we have;

x = n × p'

A. The point estimate, x', corresponding to the population proportion, p' = 69%, is given as follows;

x = 1,390 × 69/100 ≈ 959 (we round down to the nearest whole number (college graduate)

Therefore;

The point estimate corresponding to the population proportion, x = 959

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
