If the null hypothesis is H0: μ ≥ 1250, then we have a left-tailed test.

True of False

Homework Answers

Answer #1

Answer : True

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

If the null hypothesis is H0: 1250; The alternative hypothesis which is the complement of Null hypothesis is

H1: < 1250;

If Alternative hypothesis has '<' - Left tailed

If Alternative hypothesis has '>' - Right tailed

If Alternative hypothesis has '' - Two tailed.

Therefore,

If the null hypothesis is H0: 1250, then we have a left-tailed test.- True

For the following hypothesis test, where H0: μ ≤ 10; vs. HA: μ > 10, we reject H0 at level of significance α and conclude that the true mean is greater than 10, when the true mean is really 14. Based on this information, we can state that we have: Made a Type I error. Made a Type II error. Made a correct decision. Increased the power of the test.
