    parameter tested=σ (population standard deviation)

    two tailed

    Step-by-step explanation:

    We are given that null hypothesis that σ is equal to 88 and alternative hypothesis that σ is not equal to 88. The parameter that is tested here is σ.

    σ denotes the population standard deviation. Thus, the population parameter σ is tested here.

    The type of test depends on the alternative hypothesis we have taken. The alternative hypothesis states that σ is not equal to 88. It means that σ can either be greater than 88 or less than 88. Thus, the test can either be right tailed or left tailed. This type of test is called as two tailed test.
