Suppose that 30 people have been asked in a survey about how many hours they spend watching TV per day. Then, use these data to find a 95% confidence interval for the mean amount of time spent watching TV is 1.5 to 3.2 hours. Which statement is NOT true?

A. We are 95% confidence to conclude that the mean amount of time spent watching TV is between 1.5 and 3.2 hours.

B. The probability that the true value of the mean amount of time spent watching TV falls between (1.5,3.2) is roughly 95%.

C. 99% confidence intervals calculated from the same data will be wider than (1.5,3.2).

D. Any value between (1.5,3.2) is a good guess at the possible value of the mean amount of time spent watching TV.
