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.

Prove or disprove that a linear relationship exists between x and y when testing a hypothesis concerning β1. Is there overwhelming evidence at the α = .10 level of a relationship between the price of the tractors and their respective age for a two-sided test and where H0: β1 = 0? Compute the critical value for n = 5 and calculate the test statistic. The asking price of a used tractor is given for a sample size of five. Age...

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 (1) What are the restricted and unrestricted regressions?...
