A researcher conducts a repeated-measures study to evaluate a treatment with a sample of n = 16 participants and obtains a t sta

Sedaia [141]

Answer:

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

$t_{statistic} = 1.94$

$\alpha = 0.05$

Now,

Right One-tail Test

$t_{critical} \text{ at 0.05 level of significance, 15 degree of freedom } = 1.753$

$t_{stat} > t_{critical}$

We reject the null hypothesis in this case.

Two-tail Test

Now, $t_{critical} \text{ at 0.05 level of significance, 9 degree of freedom } = \pm 2.131$

$-2.131 < t_{stat} < 2.131$

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.

9/20 + 2 9/10 or nine twentieths plus two and nine tenths

seropon [69]

So, first we have to put in an equation

9/20+ 2 9/10

multiply 9/10 by 2

So you get 9/20+ 2 18/20

Add the fractions together and you'll get 26/20

since their isn't a whole number a whole number it's just 2 and 26/20 reduce it to

2 and 9/5

I hope this is right. This is how I was taught.
