Question
Background: Henry Cavendish carried out a series of experiments in 1798 to determine the mean density of
the earth, as an indirect means to calculate the gravitational constant. A measurement of 5.5 indicates the
earth's density is 5.5 times that of water.
Source: Cavendish, H. (1798). Experiments to determine the density of the
earth. Philosophical Transactions of the Royal Society of London, 88 (Part II),
469-527.
Directions: Perform an appropriate significance test to determine whether or
not Henry Cavendish's measurements for the density of the earth were
different from the true value of 5.513.

b. Compute the test statistic. Round your answer to 4 decimal places.
c. Compute the p-value. Round your answer to 4 decimal places.
d. Interpret the results of the test.
O The p-value provides strong evidence against the null hypothesis. The difference
between Henry Cavendish's measurements for the density of the earth and the true value
are statistically significant.
O The p-value provides little evidence against the null hypothesis. The difference between
Henry Cavendish's measurements for the density of the earth and the true value are not
statistically significant.
