**Finding Critical Values and Rejection Regions for a Z-Test**In this exercise, we focus on determining the critical value(s) and corresponding rejection region(s) for a two-tailed z-test with a specified level of significance, denoted by α.**Parameters:**- **Test Type:** Two-tailed- **Level of Significance (α):** 0.07**Task:**- Calculate the critical value(s), z- Round the results to two decimal places- If there is more than one critical value, separate them with a comma**Instructions:** Determine the critical z-values that separate the acceptance region from the rejection regions on a standard normal distribution curve. These values are crucial in decision-making processes, determining whether to reject or fail to reject the null hypothesis.**Graph Explanation:**A typical graph accompanying this task would depict a normal distribution (bell curve) with two shaded areas in the tails. These shaded areas represent the rejection regions, each containing 0.035 of the data (since α/2 = 0.035 for a two-tailed test with α = 0.07). The critical z-values form the boundaries between the rejection regions and the central acceptance region of the graph.

The objective is to find the critical value(s) and rejection region(s) for the given type of z test. From the given information, the test is a two tailed test. Level of significance Compute the critical value(s). Since, given test is a two tailed test, there will be two critical values. The critical values are z = -1.81, 1.81. Rejection rule: Reject the null hypothesis, if z < -1.81 and z > 1.81. For the two-tailed test, the rejection region lies at the tail area. Therefore, the graph of the rejection region is,
