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

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

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

Step 1of 2:

Sixty- four independent measurements were made of the speed of light. The average speed is 299,795 Km/s, and standard deviation is 8 km/s.
