A baseball coach was curious about the true mean speed of fastball pitches in his league. The coach recorded the speed in kilometers per hour of each fastball in a random sample of 100 pitches and constructed a 95% confidence interval for the mean speed. The result- ing interval was (110, 120).. Which of the following is a correct interpretation of the interval (110, 120)? A B с D If the coach took another sample of 100 pitches, there is a 95% chance the sample mean would be between 110 and 120 km/hr. About 95% of pitches in the sample were between 110 and 120 km/hr. There is a 95% confidence that the interval (110, 120) captured the true mean pitch speed. It is probably that the sample mean is the same as the population mean 95% of the time.
