A company performs linear regressions to compare data sets for two similar
tensa zangetsu [6.8K]

Based on the information given, the thing that can be concluded is that Brand A's data are probably linear while Brand B's data are probably not.

<h3>What is a Linear regression?</h3>

It should be noted that a linear regression simply shows the relationship between the dependent and independent variables.

If residuals for brand A are randomly scattered above and below the x-axis, and the residuals for brand B are also randomly scattered but clustered closer to the x-axis, it implies that brand A's data are probably linear while Brand B's data are probably not.

A random scatter of points on the residual plot simply implies that there's a linear relationship in the original data set.

Pani would pay $59 if she gets a discount of $3 on each shirt and $3 on each jeans

Step-by-step explanation:

Given

Price of shirt = $12

Price of jeans = $19

Price of shirt after $3 discount = 12-3 = $9

Price of jeans after 3 discount = 19-3 = $16

So

The total money Pani has to pay will be:

9(3)+16(2)\\=27+32\\=\$59

Pani would pay $59 if she gets a discount of $3 on each shirt and $3 on each jeans

Keywords: Discount, percent
