      In Alternative hypothesis,
      only less than or greater than, then, one-tailed.
      "Not equal to" - two-tailed.

    mam i got Z= -2.8288 then z is less than 2.58 hence it accept h0
    is it right..?

      Yes. Correct. But 2.8288 > 2.58. So Reject Ho, and mention the level of significance in the conclusion. Consider the absolute value for comparison.😊
