assume ( h_0: mu leq 6 ) and ( h_a: mu > 6 ). is this a left - tailed, right - tailed, or two - tailed test?
○ a. this is a left - tailed test.
○ b. this is a right - tailed test.
○ c. this is a two - tailed test.

Explanation:

In hypothesis testing, the type of test (left - tailed, right - tailed, or two - tailed) is determined by the alternative hypothesis \(H_a\).

• For a left - tailed test, \(H_a:\mu<\text{value}\).
• For a right - tailed test, \(H_a:\mu>\text{value}\).
• For a two - tailed test, \(H_a:\mu

eq\text{value}\).

Here, \(H_a:\mu > 6\), which matches the form of a right - tailed test.

Answer:

B. This is a right - tailed test.
