Astatistics practitioner in a large university is investigating the factors that affect salary of professors. he wondered if evaluations by students are related to salaries. to this end, he collected 100 observations on:
y = annual salary (in dollars)
x = mean score on teaching evaluation
to accomplish his goal, he assumes the following relationship:
y = β(0) + β(1)x + ξ
then, using excelâs data analysis, he obtained the following result.
r2=0.23
coefficient standard error
intercept 25675.5 11393
x 5321 2119
what is the p-value?
select one:
a. 0.02
b. 0.01
c. 0.17
d. 0.34
