The test statistic of z=2.48 is obtained when testing the claim that p > 0.7.

(a) identify the hypothesis test as being two-tailed, left-tailed, or right-tailed.
(b) find the p-value.
(c) using a significance level of alpha=.05, should we reject h0 or should we fail to reject h0?

a)  Right-tailed test

b) 0.006569

c) We reject .

Step-by-step explanation:

We are given the following information in the question:

We are testing the claim  that p > 0.7

Alpha, α = 0.05

a) We have to identify type of test.

Since we test for claim p > 0.7, it is a one-tailed(right) test.

b) The p-value can be calculated with the help of standard normal table.

C) Since the p-value is less than the significance level, we fail to accept the null hypothesis and reject the null hypothesis.

Thus, we reject .

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
