Question

What is the type of the hypothesis being tested and whether it is left-tailed, right-tailed, or two-tailed? What parameter is being tested when the null hypothesis is H0: p = 0.7?

1) Type I error
2) Type II error
3) One-tailed test
4) Two-tailed test

Answer 1

The hypothesis being tested is H0: p = 0.7 and it is a two-tailed test.

Step-by-step explanation:

The null hypothesis being tested is H0: p = 0.7, where p represents a population parameter. When testing this null hypothesis, we are looking to determine if the true population proportion is equal to 0.7 or not. The alternative hypothesis, Ha, tells us whether the test is left-tailed, right-tailed, or two-tailed. In this case, since the alternative hypothesis is not specified, we consider it a two-tailed test. A two-tailed test looks for discrepancies in both directions from the null hypothesis value.
