A health organization collects data on hospitals in a large metropolitan area. The scatterplot shows the relationship between two variables the organization collected: the number of beds each hospital has available and the average number of days a patient stays in the hospital (mean length of stay). Which statement best explains the relationship between the variables shown? Hospitals with more beds cause longer lengths of stay. The size of the hospital does not appear the have an influence on length of stay. More complex medical cases are often taken by larger hospitals, which increases the lengths of stay for larger hospitals. More complex medical cases are often taken by larger hospitals, which decreases the lengths of stay for larger hospitals.

Breast-feedingmothers secrete calcium into their milk. Some of thecalcium may come from their bones, so mothers maylose bone mineral. Researchers measured the percent changein mineral content of the spines of 47 mothers during threemonths of breast-feeding.6 Here are the data: -4.7 -2.5 -4.9 -2.7 -0.8 -5.3 -8.3 -2.1 -6.8 -4.32.2 -7.8 -3.1 -1.0 -6.5 -1.8 -5.2 -5.7 -7.0 -2.2-6.5 -1.0 -3.0 -3.6 -5.2 -2.0 -2.1 -5.6 -4.4 -3.3-4.0 -4.9 -4.7 -3.8 -5.9 -2.5 -0.3 -6.2 -6.8 1.70.3 -2.3 0.4 -5.3 0.2 -2.2 -5.1 (a) The researchers are willing to consider these 47women as an SRS from the population of all nursingmothers. Suppose that the percent change in this population has standard deviation 2.5%. Make a stemplotof the data to verify that the data follow a Normal distribution quite closely. (Don’t forget that you need botha 0 and a 0 stem because there are both positive andnegative values.) (b) Use a 99% confidence interval to estimate the meanpercent change in the population
