Ga. at the 0.05 level of significance, is there evidence that the mean difference is different from 0.0 inches? b. after looking at the results using the upper critical value test, we see that there is not enough evidence to conclude that the mean difference is different from 0.0 inches. c. construct a 95% confidence interval estimate of the population mean. interpret this interval. d. compare the conclusions reached in (a) and (b). e. because n = 100,n = 100, do you have to be concerned about the normality assumption needed for the t test and t interval?

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

the correct option is b
