A candy bar manufacturer is interested in trying to estimate how sales are influenced by the price of their product. To do this, the company randomly chooses 6 small cities and offers the candy bar at different prices. Using candy bar sales as the dependent variable, the company will conduct a simple linear regression on the data below: If the price of the candy bar is set at $2, the estimated mean sales will be: City Price ($) Sales River Falls 1.30 100 Hudson 1.60 90 Ellsworth 1.80 90 Prescott 2.00 40 Rock Elm 2.40 38 Stillwater 2.90 321. Referring to the above Table , what is the estimated slope parameter for the candy bar price and sales data?
2. Referring to the above Table, what is the estimated average change in the sales of the candy bar if price goes up by $1.00?
3. Referring to Table, what is the coefficient of correlation for these data?
4. Referring to Table , what is the percentage of the total variation in candy bar sales explained by the regression model?
5. Referring to Table , what percentage of the total variation in candy bar sales is explained by prices?
