PLEASE Show me how to calculate this

A regression analysis is performed using data for 34 single-family homes to predict appraised value (in thousands of dollars) based on land area of the prope (in acres), Xi, and age (in years), X2i in month i. Use the results below to complete parts (a) and (b) below. Standard Variable Coefficient Error St Intercept 403.71176 50.59445 7.98 0.0000 Area, X459.76542 113.33619 4.06 0.0003 X291911 065316447 0.001 a. Construct a 95% confidence interval estimate of the population slope between appraised value and land area.

Explanation / Answer

here for (n-p =34-3=31) degree of freedom ;at 95% CI critical value of t =2.0395

therefore 95% confidence interval for populaiton slope =estimated value -/+ t*std error

=459.76542 -/+ 2.095*113.33619 =222.3261 <beta 1 <697.2047
