Question

The results of a sample of 7 data points are presented below in terms of the Average Daily Temperature (^oF) and the Average Monthly Precipitation (inches):

Average Daily temperature x	86	81	83	89	80	74	64
Average Monthly Precipitation y	3.4	1.8	3.5	3.6	3.7	1.5	0.2

d- Determine the regression line equation

e- Plot the regression line on the scatter plot (on same graph)

f- Calculate the standard error of estimate

g- Find the 95% prediction interval for the 95^oF average daily temperature

Expert Solution

Step 1

“Since you have posted a question with multiple sub-parts, we will solve the first three sub-parts for you. To get the remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.”

Given:

n = 7

Formula Used:

The equation of regression line is:

Y = a + bX

$b = \frac{n \sum_{}^{} XY - \sum_{}^{} X \sum_{}^{} Y}{n \sum_{}^{} X^{2} - {(\sum_{}^{} X)}^{2}}$
