Question 2

HEre for business majors

t = 0.348999 and p - value = 0.7299 > 0.10

so,

y^ = 29.7917 + 4.7985 * x1 - 12.9993 * x2 + 0.2714 * x3

where x1 =4

x2 = 1

x3 = 0 (no business degree)

y^ = 29.7917 + 4.7985 * x1 - 12.9993 * x2 + 0.2714 * x3

y^ = 29.7917 + 4.7985 * 4 - 12.9993 * 1 = 35.9864 = $ 35986
