Perform statistical inference for multiple regression.
-What affects flat panel LCD TV sales? Flat panel LCD TV's are sold through a
Variety of outlets. Sales figures (number of units) for the popular Sony Bravia were
Obtained for last quarter from a sample of 30 different stores. Also collected were data
On the selling price and amount spent on advertising the Sony Bravia (as a percentage of
Total advertising expenditure in the previous quarter) at each store. Output is shown
Below. The calculated t-statistic to determine if amount spent on advertising is a
Significant independent variable in explaining Sony Bravia sales is $\text {Dependent Variable is Sales}$
