Question

Stephen Stigler determined in 1977 that the speed of light is 299,710.5 km/sec. In 1882, Albert Michelson had collected measurements on the speed of light ("Student t-distribution," 2013). Is there evidence to show that Michelson’s data is different from Stigler’s value of the speed of light? Match the random variable, population parameter, and hypotheses statements with their correct definitions (not all definitions will be used!).

Question 1 options:

1234567

random variable x

1234567

alternate hypothesis HA

1234567

population parameter p

1234567

null hypothesis Ho

? = mean speed of light measured by Albert Michelson

x = speed of light measured by Stephen Stigler

x = speed of light measured by Albert Michelson

? > 299,710.5 km/s

? = 299,710.5 km/s

? < 299,710.5 km/s

? ? 299,710.5 km/s

1.

? = mean speed of light measured by Albert Michelson

2.

x = speed of light measured by Stephen Stigler

3.

x = speed of light measured by Albert Michelson

4.

? > 299,710.5 km/s

5.

? = 299,710.5 km/s

6.

? < 299,710.5 km/s

7.

? ? 299,710.5 km/s

Explanation / Answer

ANSWERS:

1) ? = mean speed of light measured by Stephen Stigler

2) X = speed of light measured by Stephen Stigler

3) x = speed of light measured by Albert Michelson

4) Ho: ? = 299,710.5 km/s

5) H1: ? ? 299,710.5 km/s

( ? > 299,710.5 km/s, ? < 299,710.5 km/s, bothe are one sided alternative hypothesis). But in question asked two sided hypothesis
