You are testing the null hypothesis that there is no linear relationship between two variables, X and Y. From your sample of n =18, you determine that b1=5.1 and Sb1 =1.1
a. What is the value of tSTAT?
b. At the α=0.05 level of significance, what are the critical values?
c. Based on your answers to (a) and (b), what statistical decision should you make?
d. Construct a 95% confidence interval estimate of the population slope, β1.
I would greatly appreciate it if you answered this question quickly, I'm very pressed for time. Thank you so much.

Concept Questions
We've discussed that a linear regression assumes the
relationship between variables is linear: it forms a constant
slope. But suppose the data is U-shaped or inverted U-shaped. How
would you created a linear regression so the line would follow this
data? (hint: think of what the equation for a U-shaped line looks
like.)
Suppose you applied a scalar to a variable. Then you used both
the original variable and the scaled variable as explanatory
variables. What would happen...

Hypothesis testing--F test for two variables
Suppose that you wants to test whether the returns on a company
stock (y) show no sensitivity to two factors (factor x2 and factor
x3) among three considered. That is, the null hypothesis is: β2=0,
β3=0. The regression is carried out on 144 monthly observations,
which means the sample size is 144. The regression is:
y = β1 + β2x2 + β3x3 + β4x4 + u
