Test the significance of the slope and y-intercept

Please, I need assistance building an excel doc, as well as detailed understanding of the placement, thank you.

Information:
A real estate agency collects data concerning y = the sales price of a house (in thousands of dollars), and x = the home size (in hundreds of square feet). The MINITAB output of a simple linear regression analysis of the data set for this case is given in table (below).

(a) Find the least squares point estimates b0 and b1 of β0 and β1 on the output and report their values.(Round b0 to 2 decimal places and b1 to 4 decimal places.)

b0 ______
b1 ______

(b) Find SSE and s on the computer output and report their values. (Round SSE to 1 decimal place and s to 3 decimal places.)

SSE _______
s _______

(c) Find sb1 and the t statistic for testing the significance of the slope on the output and report their values. Show (within rounding) how t has been calculated by using b1 and sb1 from the computer output. (Round sb1 to 4 decimal places and t to 2 decimal places.)

sb1 _______
t _______

(d) Using the t statistic and appropriate critical value, test H0: β1 = 0 versus Ha: β1 ≠ 0 by setting α equal to .05. Is the slope (regression relationship) significant at the .05 level?

(Choose one) Reject / Do Not Reject not reject

H0. The slope is (Choose one) Not Significant / Significant at the .05 level.

(e Using the t statistic and appropriate critical value, test H0: β1 = 0 versus Ha: β1 ≠ 0 by setting α equal to .01. Is the slope (regression relationship) significant at the .01 level?

(Choose one) Do not reject / Reject

H0. The slope is (Choose one) Not Significant / Significant at the .01 level.

(f) Find the p-value for testing H0: β1 = 0 versus Ha: β1 ≠ 0 on the output and report its value. Using the p-value, determine whether we can reject H0 by setting α equal to .10, .05, .01, and .001. How much evidence is there that the slope (regression relationship) is significant? (Round your answer to 3 decimal places.)

p- value = _________ reject at (Choose one )
none
all α.
10 and .05

(g) Calculate the 95 percent confidence interval for β1 using numbers on the output. (Round your answers to 4 decimal places.)

(h) Calculate the 99 percent confidence interval for β1 using numbers on the output. (Round your answers to 3 decimal places.)

[ ______ , _______ ]

(i) Find sbo and the t statistic for testing the significance of the y intercept on the output and report their values. Show how t has been calculated by using b0 and sb0 from the computer output. (Round your answers to 2 decimal places.)

sb0 ___________________
t ___________________

(j) Find the p-value for testing H0: β0 = 0 versus Ha: β0 ≠ 0. Using the p-value, determine whether we can reject H0 by setting α equal to .10, .05, .01, and .001. What do you conclude about the significance of the y intercept? (Round your answer to 3 decimal places.)

p-value = __________

None

(k) Using the appropriate data set and s from the computer output, hand calculate SSxx, sbo, and sb1. (Round your answers for SSxx to 1 decimal place and sb1 to 4 decimal places and sb0 to 2 decimal places.)
