What is the y-intercept of the best fit line between the temperature (x) and the number of customers (y)? Round your answer to four decimal places.
Homework Answers
The statistical software output for this problem is:
Simple linear regression results:
Dependent Variable: Y
Independent Variable: X
Y = 12.081291 + 0.94997591 X
Sample size: 10
R (correlation coefficient) = 0.97550679
R-sq = 0.9516135
Estimate of error standard deviation: 8.1648331
Parameter estimates:
| Parameter | Estimate | Std. Err. | Alternative | DF | T-Stat | P-value |
|---|---|---|---|---|---|---|
| Intercept | 12.081291 | 4.8109621 | ≠ 0 | 8 | 2.5112007 | 0.0363 |
| Slope | 0.94997591 | 0.075735483 | ≠ 0 | 8 | 12.54334 | <0.0001 |
Hence,
y - intercept = 12.0813

The following data lists temperature (x, in degrees Fahrenheit) and sales (y, in dollars) for 15 random days at an ice cream shop. At the 5% significance level, use Excel to test the claim that temperature and ice cream sales are linearly related by specifying the slope estimate, p-value and final conclusion below. Do not round any intermediate calculations. Round your slope estimate answer to 2 decimal places. Round your p-value to 4 decimal places. Enter a "−" sign in...
