Question

the null and alternative hypotheses are given. determine whether the hypothesis test is left - tailed, right - tailed, or two - tailed. what parameter is being tested?
$h_{0}:\sigma = 6$
$h_{1}:\sigma>6$
what type of test is being conducted in this problem?
two - tailed test
right - tailed test
left - tailed test

Explanation:

In hypothesis testing, if the alternative hypothesis \(H_1\) has a "greater than" (\(>\)) sign, it indicates a right - tailed test. Here, \(H_1:\sigma>6\) (where \(\sigma\) is the population standard deviation). A left - tailed test would have \(H_1\) with a "less than" (\(<\)) sign, and a two - tailed test would have \(H_1\) with a "not equal to" (\(
eq\)) sign.

Answer:

Right - tailed test.
