a. Find the critical value(s).
Select the correct choice below and fill in the answer box(es) within your choice.
(Round to two decimal places as needed.)
O A. There is one critical value, the critical value is
OB. There are two critical values; the lower critical value is
and the upper critical value is

Answer 1

The answer is: There is one critical value, the critical value is 1.6449.

Finding the Critical Value(s)

Since this is a right-tailed test with a significance level of 0.05, we need to find the critical value that cuts off 0.05 area in the right tail of the standard normal distribution.

There is one critical value for this test.

We can find it by looking up the area 0.95 (1 - 0.05) in the standard normal distribution table.

Critical value = 1.6449

Therefore, the answer is:

There is one critical value, the critical value is 1.6449.
