s) Are teacher salaries in ABC Academy, lower than those in XYZ Academy? Salary data provided shows teachers in Academy earn less than those in XYZ Academy. Suppose that in a follow-up study of 50 teachers in ABC Academy a 55 teachers in XYZ Acadmey, you obtain the following result. In addition, based on past studies, a standard deviati o; for both schools were obtained. АВС XYZ x = 188300 X2 = 178900 %3D 0, = 19600 02 = 16250 Formulate hypotheses so that, if the null hypothesis is rejected, we can conclude that given a 90% confidence, that salaries for teachers in ABC Academy are significantly greater than those in XYZ Academy.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
