given that a test statistic in a left tailed test is z equals -1.25, use a 0.05 significance level to find the p-value and state
mr Goodwill [35]

Answer:

The <em>p-</em>value of the test is 0.106.

The null hypothesis will be accepted at 5% level of significance.

Step-by-step explanation:

The hypothesis test is left-tailed.

The test statistic value is: <em>z</em> = -1.25.

The significance level of the test is: <em>α</em> = 0.05.

The <em>p</em>-value of a left-tailed hypothesis test is:

p-value=P(Z

The <em>p-</em>value of the test is 0.106.

**Use the <em>z-</em>table for the probability.

<u>Decision rule:</u>

If the <em>p</em>-value is less than the significance level the null hypothesis will be rejected and if it is more than the significance level the null hypothesis will be accepted.

The <em>p</em>-value = 0.106 > <em>α</em> = 0.05.

The null hypothesis will be accepted at 5% level of significance.

Find the value of x.
Paul [167]

Hello!

As we are looking for the opposite side and hypotenuse, we will use the sine.

sin30=1/2

This gives us the equation below.

1/2= 5/x

1/2x=5

x=10

Therefore, x=10.

I hope this helps!
