6. two separate samples receive different treatments. after treatment, the first sample has n = 9 with ss = 462, and the second has n = 7 with ss = 420. a. compute the pooled variance for the two samples. b. calculate the estimated standard error for the sample mean difference. c. if the sample mean difference is 10 points, is this enough to reject the null hypothesis using a two-tailed test with α = .05? gravetter, frederick j. statistics for the behavioral sciences (p. 329). cengage learning. kindle edition.

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

i need the table so i can see

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
