1. A consulting company is hired to investigate the relationship between average physician annual income and number of beds present at a local hospital. Assume the following table represents a SRS of hospitals.

Average Physician Annual Income($/year, X)	Number of Beds (Count, Y)
127,655	698
176,526	943
134,253	713
114,534	578
116,549	498
167,547	889
149,863	769
176,546	937
149,537	776
153,649	813
126,349	678

A) Calculate basic descriptive statistics for your X and Y variables. (3 points)

B) Calculate a correlation coefficient, and interpret your result with respect to strength and direction. (2 points)

C) Calculate and correctly interpret your r² for the data. (2 points)

D) Can we consider the relationship causal? For instance, can we claim that the higher the physician average income at a hospital, the more beds the hospital has? (1 points)
