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: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
