The hypothesis test for the proportions is calculated using a z test statistic since proportions are based on a binomial distribution. True or False
Homework Answers
Answer:-
Given statement is True
Because in case of proportion test we consider number of success (x) out of (n) trials and p is ratio of this two ,so in this case we consider binomial distribution threfore the hypothesis test for proportion is calculated using a z test statistic since proportion are based on a binomial distribution.

True or False The model used for hypothesis testing of proportions is called a two-proportion z-test. True or False Beta (β) is the significance level which determines if the null hypothesis is rejected. True or False In business, the p-value is one of several factors in determining whether or not to reject a null hypothesis. True or False We could make a decision to reject a null hypothesis on a very low p-value or a very high z score.

When the necessary conditions are met, a two-tailed test is being conducted to test the difference between two population proportions. The two sample proportions are p1hat=0.052 and p2hat=0.023 and the standard error of the sampling distribution of p1-p2 is 0.0085. The calculated value of the test statistic will be z = 3.41. A. True B. False

Identify the null hypothesis,
alternative hypothesis, test statistic, P-value, conclusion about
the null hypothesis, and final conclusion that addresses the
original claim. Use the P-value method. Use the normal
distribution as an approximation of the binomial distribution.
