Answer:
the second equation converted to slope-intercept form is y = -1/3x -1
Step-by-step explanation:
If given a line in the slope-intercept form
y=mx+b
m is the slope and b is they y-intercept

According to the desired test, the test that should be conducted is:
- (B) A one-sided, two-sample t-test
<h3>Test:</h3>
- At the null hypothesis, it is tested if Brand A batteries do not last longer than Brand B batteries, that is, the result of the subtraction is of at most 0:

- At the alternative hypothesis, it is tested if it is greater, that is:

The factors determining the test used are as follows:
- We can find the <u>standard deviation for the sample</u>, hence a t-test is used.
- There are two samples, the lifetimes for batteries A and for batteries B, hence, a two-sample test is used.
- We are testing if one mean is greater than another, and more than/less than tests are one-sided.
- Hence, option B is correct.
