A regression was run to determine if there is a relationship between hours of study per week (x) and the test scores (y). The results of the regression were: y=ax+b a=5.235 b=21.73 r²-0.36 r=0.6 Use this to predict the final exam score of a student who studies 1 hours per week, and please round your answer to a whole number.

Claim: The mean systolic blood pressure of all healthy adults is less than 122 mm Hg. Sample data: For 269 healthy adults, the mean systolic blood pressure level is 121.74 mm Hg and the standard deviation is 15.02 mm Hg. Complete parts (a) and (b). a. Express the original claim in symbolic form. Let the parameter represent a value with respect to systolic blood pressure of a healthy adult.
