Question

For a right tail confirmation of a hypothesis test, you use the following confidence interval:

? > x + E

? < x + E

x - E < ? < x + E

? > x - E

Answer 1

Solution :-

For a right tail confirmation of a hypothesis test, you use the following confidence interval:

Ans :-

? < x + E

------------------------------------------------------

u = Population Mean

X = Sample Mean

E = Margin of error

? > x - E -- this is to be used for left tail

x - E < ? < x + E - this is to be used for both tail

Confidence intervals and hypothesis tests are similar in that they are both inferential methods that rely on an approximated sampling distribution. Confidence intervals use data from a sample to estimate a population parameter. Hypothesis tests use data from a sample to test a specified hypothesis. Hypothesis testing requires that we have a hypothesized parameter.
