A report by the Gallup Poll found that a woman visits her doctor, on average, at most 5.8 times each year. A random sample of 20 women results in these yearly visit totals. 3; 2; 1; 4; 7; 2; 9; 4; 6; 6; 8; 0; 5; 6; 5; 2; 1; 3; 4; 1 At the ? = 0.05 level can it be concluded that the sample mean is higher than 5.8 visits per year? Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) State the p-value. (Round your answer to four decimal places.) What is your decision? State conclusion.
