Consider the following hypothesis test.

h0: μ1-μ2=0
ha: μ1-μ2 ! =0

the following results are from independent samples taken from two populations.
sample1 sample2
n1=80 n2=70
x1=104 x2=106
σ= 8.4 σ=7.6

a. what is the value of the test statistic?
b. what is the degrees of freedom for the t distribution?
c. what is the p-value?
d. at a = 0.05, what is your conclusion?

-6 is the correct option from the above given options

answer: this is not a question

step-by-step explanation: this is a answer

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

probably .5

i can on others if necessary.
