Homework Help: Simple linear regression model

  1. Dec 22, 2017 #1
    1. The problem statement, all variables and given/known data
    For the first question , why when the humidity increase by 1 percent , the moisture content will increase by 0.2727 percent ? Shouldn't it the moisture content will increase by 0.2727 + 0.4911 percent when the humidity increase by 1 percent ???
    Second question , it's clear that in the 2nd photo , the slope , B_1 is 0.2724. It's is to test whether the slope equal to 1 in example 5 .. Why at the end of result , we should do not reject H0 , and conclude that B_1 is 1 ?
    P/s : Example 5 (3rd and 4th photo) is continuous from example 3 (first and second photo)
    2. Relevant equations


    3. The attempt at a solution

    I think for the second question is wrong . It's clear that in example 3 the B_1 is 0.2724 , which is not 1 . So , i think we should reject H0 , so that the slope , B_1 not equal to 1 . Correct me if i am wrong .

    You should not expect helpers to look at your posted images. If you are serious about wanting help, you should type out the problem statement and the final regression equation. You can include the image of the data table---that is acceptable.

    You should read the "pinned" thread "Guidelines for students and helpers" by Vela, to get a better idea of PF standards and recommendations.
