An education researcher claims that at most 3% of working college students are employed as teachers or teaching assistants. In a random sample of 400 working college students, 5% are employed as teachers or teaching assistants. At a = 0.10, is there enough evidence to reject the researcher's claim? Complete parts (a) through (e) below. Ha: p Ha p< Ha p>|0.03| (b) Find the critical value(s) and identify the rejection region(s). Identify the critical value(s) for this test Z0 =-128 (Round to two decimal places as needed. Use a comma to separate answers as needed.) Identify the rejection region(s). Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to two decimal places as needed.) O A. The rejection region is Oc. The rejection region is z< O D. The rejection region isz>-1.28 (C) Find the standardized test statistic z. z= 2.34 (Round to two decimal places as needed.) (d) Decide whether reject or fail to reject the null hypothesis and (e) interpret the decision in the context of the original claim.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
