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.

A researcher surveyed 80 patients at a certain hospital. The histogram below gives the length of time patients waited to see a doctor at the hospital. The classes, in minutes, are 0 - 1.9, 2 - 3.9, etc., and the vertical axis represents the number of patients. 25 20 15 10 2 4 8. 10 wait time (minutes) (a) Use the histogram to determine the percent of patients that waited less than 6 minutes to see the doctor. (b) Determine the interval that contains the median wait time. **Include all decimal places** number of patients
The table pertains to scheduled commercial carriers. Fatalities data include those on the ground except for the September 11, 2001, terrorist attacks. Use this information given in the table. For fatalities the mean an = 66.7 the median = 14.5 and the mode = 2 2. The year 2001 was clearly an anomaly. If the data for that year is reduced by 239 fatalities, which of the three measures change and what are their new values for each of the following? please help:(
