R12 = 0.6562 implies that 65.62% of the variation of weekly sales (Y) around its mean (y-bar) is explained by the independent variables Price for store size (X). Thus, the fitted line is a good fit to the data and the model seems to be accurate.
Regression Equation: Y = 1612.467 + 3.110897 (X)
Intercept = 1612.467, which tells me the initial value of Weekly sales (Y) when store size (X) is zero. Slope = 3.11 which tells the us that there is 3.11 units increase in weekly sales (Y) when there is unit increase in store size (X).

Hypothesis Testing:
Ho1: β1=0, β1 is not significant
v/s H11: β1≠0, β1 is significant.
p-value = 0.0000
Since p-value < 0.05, reject H01 at 5% level of significance and conclude that β1 is significant.
Thus, Store Size (X) should be included in the model.
From the data analysis, y = 1612.467 + 3.1109 x . Weekly store sales are expected to average \$5 per square foot. 1000 square foot store have average weekly sales of 5000. From this equation if x = 1000, y = 4723.367. Even there is difference between expected value and observed value. I think it is reasonable.

Conclusion
* There is strong linear positive relationship between store size and weekly sales.
* Large store size causes high weekly sales.
* Even there are differences between observed sales and expected sales, it is acceptable.
