Question
A study was done of 6 patients admitted to a hospital. Their ages (x) and systolic blood pressure (y) was recorded.
Age (x) | Systolic blood pressure (y) |
43 | 123 |
48 | 125 |
56 | 135 |
61 | 143 |
67 | 145 |
70 | 152 |
D. Compute the residual for x = 48, using the rounded slope and y intercept. Report answer to 3 decimal places.
E. The data value of x = 56 has a residual of -0.575 If you were to make a
- (56, 135)
- (48,125)
- (43,123)
- They are all the same distance from the regression line.
F. Determine the value of se, reporting to 3 decimal places.

- Develop a scatterplot and explore the correlation between customer age and net sales by each type of customer (regular/promotion). Use the horizontal axis for the customer age to graph. Find the linear regression line that models the data by each type of customer. Round the rate of changes (slopes) to two decimal places and interpret them in terms of the relation between the change in age and the change in net sales. What can you conclude?
