Scientists

On page 80 of their test, Hollander and Wolfe (1999) present measurements of the ratio of the earth’s mass to that of its moon that were made by 7 different spacecraft (5 of the Mariner type and 2 of the Pioneer type). These measurements are presented below (also in the file earthmoon.rda). Based on earlier Ranger voyages, scientists had set this ratio at 81.3035. Assuming a normal distribution, test the hypotheses H0 : μ = 81.3035 versus H1 : μ = 81.3035, where μ is the true mean ratio of these later voyages. Using the p-value, conclude in terms of the problem at the nominal α-level of 0.05.
