Clark Barr makes a claim that 10% of all students who take statistics drop out. Rosetta Stone decides to test his claim, since she believes that the dropout rate is greater than 10%. Rosetta uses a random sample of 15e`0 students currently enrolled in a statistics course. In her sample, Rosetta finds that of the 150 students, 22 dropped out. Test to determine the validity of Clark Barr’s claim at the 0.01 significance level. (Show all seven steps.)
