Stephen Stigler determined in 1977 that the speed of light is 299,710.5 km/sec. Some measurements of the
speed of light are given in the table. Is there evidence to show that the data
value of the speed of light? Test at the 1% level.

O Since the p-value is greater than 0.01, fail to reject Ho.
O Since the p-value is less than 0.01, reject Ho.
Interpret the results.
O At the 1% level of significance, there is not enough evidence to conclude that the mean speed of
líght determined by the data is not equal to 299,710.5 km/s.
