Referring to the table, which of the following will be a correct conclusion? A researcher would like to analyze the effect of muscle injury on the number of physical therapy intervention programs received. She takes a random sample of 4 patients. For these 4 patients, she finds out how many times each had a muscle injury and how many physical therapy intervention programs they received. These data are presented in the table below:

Patient Number of Muscle Injuries Number of Physical Therapy Programs Received
1 1 4
2 2 6
3 1 3
4 0 1

The results of the simple linear regression are provided below.

Y= 1+2.5X; S subscript Y X end subscript = 0.5, S subscript b 1 end subscript = 0.35355; 2-tailed p value = 0.0192 (testing beta 1)
