Step-by-step explanation:
The simple regression model is:
, then
.
The statistic calculated for the hypothesis test of statistical significance, for the slope, in a simple regression model is given by:

with
the slope estimator,
the value of slope in the null hypothesis and
the standard error of the slope. Thus,

No, she is not correct. Since the difference in each x is not constant, it would be an exponential function. It is multiplied at a rate of 3 times the previous number
