Question

For full credit, run the appropriate test of significance (explicitly stating your null hypothesis) and make a valid inference.

The statue outside of a museum was constructed to have a height of 120 feet. Engineers measure the statue’s height 3 times and get the following values (in feet):

126 116 121

Is the difference between the mean of the engineers’ measurements and the “official” value of 120 feet statistically significant?
