1. Scatter Plot-using data above can you explain how to formulate a scatter plot.

2. Regression Equation-Put the regression equation here.

3. Coefficient of Correlation-what is the value of the coefficient of coefficient. What type correlation is it and what strength

4. Coefficient of Determination-Give the value of the coefficient of determination. Interpret its value.

5. Results of the Hypothesis Test with a significance level of .05.

for Ho: B1 = 0 Ha: B1 0

p-value: put the p-value

Result of test: Explain whether you will reject not reject

Ho.

6. Explain hypothesis test above. Is the regression model (regression equation) significant in predicting the dependent variable? Why?

7. 95% confidence interval for B1

8. A. How many sales can we expect (estimate) for a sales person who made 140 calls? Estimated amount sales: Put the predicted value of SALES

here.
