Data are collected on the relationship between the number of hours per week practicing a musical instrument and scores on a math test. The line of best fit is as follows: ŷ = 72.5 + 2.8x.
What would you predict the score on a math test would be for a student who practices a musical instrument for 1.2 hours a week? Round to one decimal place.

Expert Solution
ŷ = 72.5 + 2.8x
x = 1.2
ŷ = 72.5 + 2.8 * 1.2 = 75.86 = 75.9 (ans)
