please show the actual value

6-3. Regression methods were used to analyze the data from a study investigating the relationship between roadway surface temperature (x) and pavement deflection (y). The data follow. 6-9. Consider the data and simple linear regression in Exercise 6-3. (a) Find the mean deflection given that the temperature is 74.0 degrees. (b) Compute a 95%CI on this mean response. (c) Compute a 95% PI on a future observation when temperature is equal to 74.0 degrees. (d) What do you notice about the relative size of these two intervals? Which is wider and why
