The manager of a large supermarket wants to use a 95 percent confidence interval to estimate the true proportion of the market's customers who buy cookies from the market. After collecting data from a random sample of customers, he calculates the confidence interval to be (0.236,0.282)(0.236,0.282). Which one of the following statements is true?
Select one:
A. The confidence interval provides convincing evidence that more than 25 percent of the market's customers buy cookies from the market.
B. There is a probability of 0.95 that the interval from 0.236 to 0.282 captures the true proportion of the market's customers who buy cookies from the market.
C. The manager can be 95 percent confident that the sample proportion of the market's customers who buy cookies from the market is between 0.236 and 0.282.
D. The manager can be 95 percent confident that the interval from 0.236 to 0.282 captures the true proportion of the market's customers who buy cookies from the market.
