Nurses (X)            Patient Falls (Y)Mean                                            40                        200Standard Deviation                  15                        50Use the data above. Same exact data as the previous question, different question at the bottom. Research has found that the correlation between number of nurses available and number of patients falling down in hospitals is approximately  r = –0.90. This suggests that hospitals with higher nursing staffing levels tend to have fewer cases of patients falling down.For a hospital that employs 60 nurses, how many cases of patients falling down should be expected?

Given the regression equation, Y= 6 + 0.5X, where X is a score on an attitude scale and Y is a job satisfaction score, what attitude score would be predicted for a job satisfaction score of 11?

Suppose “Distribution A” had a mean of 50 and a standard deviation of 10 while Distribution B had a mean of 50 and a standard deviation of 15. An x score of 55 would be relatively…
