(a)
Using R programming, we get
b0 = 117.80
b1 = -0.76
(b)
The standard error for b0 = 5.5641711
Point estimate for b0 = 117.80
c.
The standard error for b1 = 0.1311488
Point estimate for b1 = -0.76
d.
p-value = 0.01022397
As, p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that the variable x is significant in the model.
