It is given that the independent variable x is the size of the apartment and the dependent variable y is the rent of that apartment.
00:11
For n equal to 25 observations, the regression analysis is conducted.
00:17
For the value of x equal to 1000, the x y x is given as 194 .5953946 and the h i value for the value of given x is given as 0 .049156908.
00:41
Now in part a of the regression analysis, we have to construct the 95 % confidence interval for the mean rent of the apartment, sorry mean rent of the all apartment for the values of 1000 square feet size.
01:04
For that, first we have to construct the regression equation for the given analysis.
01:10
For that, we are using the excel software and the excel procedure is enter the data in excel, select the data tab, select data analysis and in that select regression and then enter the range of the data, then select ok.

The excel output is given below.
01:37
Now using the excel output, the regression equation is obtained as y cap equal to 1177 .1208 plus 1 .0651 into the independent variable x...
