Sixty-four independent measurements were made of the speed of light. They averaged 299,795 km/s and had a standard deviation of 8 km/s. True or false:

A 95% confidence interval for the speed of light is 299,795 plusminus 1.96 km/s.

The probability is 95% that the speed of light is in the interval 299,795 plusminus 1.96.

If a 65th measurement is made, the probability is 95% that it would fall in the interval 299,795 plusminus 1.96.
