Use the following information for questions:
Data from a sample of 10 student is used to find a regression equation relating y = score on a 100-point exam to x = score on a 10-point quiz. The least squares regression equation is $\hat{y}$ = 35 + 6 x. The standard error of the slope is 2. The following hypotheses are tested:
H 0 :$β_1=0$
H a :$β_1≠0$
-What is the value of the t-statistic for testing the hypotheses?
A) -2.0
B) 2.0
C) 3.0
D) 0
