Aresearcher conducts a repeated-measures study to evaluate a treatment with a sample of n = 16 participants and obtains a t statistic of t = 1.94. the treatment is expected to increase scores and the sample mean shows an increase. which of the following is the correct decision for a hypothesis test using α = .05.
- reject the null hypothesis with either a one-tailed or a two-tailed test
- fail to reject the null hypothesis with a one-tailed test but reject with two tails
- reject the null hypothesis with a one-tailed test but fail to reject with two tails
- fail to reject the null hypothesis with either a one-tailed or a two-tailed test

Option 3) We reject the null hypothesis with one tail test and accept the null hypothesis with two tail test.

Step-by-step explanation:

We are given the following information:

n = 16

Now,

Right One-tail Test

We reject the null hypothesis in this case.

Two-tail Test

Now,

We accept the null hypothesis in this case.

Option 3) We reject the null hypothesis with one tail test and accept the null hypothesis with two tail test.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
