Question

Which of the following is NOT a requirement of testing a claim about a population proportion using a formal method of hypothesis​ testing? Choose the correct answer below. A. The lowercase​ symbol, p, represents the probability of getting a test statistic at least as extreme as the one representing sample data and is needed to test the claim. B. The conditions for a binomial distribution are satisfied. C. The sample observations are a simple random sample. D. The conditions np5 and nq5 are both satisfied.

Answer 1

A. The lowercase​ symbol, p, represents the probability of getting a test statistic at least as extreme as the one representing sample data and is needed to test the claim.

Explanation:

The conditions required for testing of a claim about a population proportion using a formal method of hypothesis​ testing are:

1) The sample observations are a simple random sample.

2) The conditions for a binomial distribution are satisfied

3) The conditions np5 and nq5 are both satisfied. i.e n: p≥ 5and q≥ 5

These conditions are given in th options b,c and d.

Option A is not a condition for testing of a claim about a population proportion using a formal method of hypothesis​ testing.
