Answer #1

Level of significance = 0.1

Confidence level = 1 - 0.1 = 0.9

Test statistic = 1.36

We have to find the critical value using the z table.

Search the value 0.9 or near value in the body of the table.

And see the corresponding row and column.

02 03 05 06 0.0 5000 5040 5080 5120 5160 5199 .5239 .5279 5319 .5359 0.1 .5398 .5438 .5478 .5517 .5557 .5596 .5636 0.2 .5793

So we get critical value = 1.28

If you have any doubt please comment!
