Homework Answers
(1) There are two types of hypotheses are as below:
i) Null Hypothesis(Ho) and
ii) Alternative Hypothesis(Ha)
(2) Null hypothesis implies a statement that expects no difference or effect. On the contrary, an alternative hypothesis is one that expects some difference or effect.
Hence, Null hypothesis is the hypothesis, which is to be actually tested, whereas alternative hypothesis gives an alternative to the null hypothesis.
(3) The required two decisions are:
i) Reject null hypothesis(Ho) and
ii) Failed to reject null hypothesis(Ho).

This means that you must provide examples of how each of these concepts can be used by upper-level management to make strategic decisions, and provide details on how statistical concepts used in the decision-making process can be summarized and presented to a board of directors (for example).: Types of statistics used for business How Computer Software Applications can be...

1. Suppose that you are testing the following hypotheses: ?0: ? = 10 and ?1: ? > 10. If the null hypothesis is rejected at the 1% level of significance, what statement can you make about the confidence interval on the mean? a.) The lower bound of a 95% one-sided confidence interval on the mean exceeds 10 b.) 9 ≤ ? ≤ 13 c.) No statement can be made d.) The lower bound of a 95% one-sided confidence interval on...

This problem is designed to give you an understanding of the methodology behind hypothesis testing. Ever wonder how someone in America can be arrested if they really are presumed innocent, why a defendant is found not guilty instead of innocent, or why Americans put up with a justice system which sometimes allows criminals to go free on technicalities? These questions can be understood by understanding the similarity of the American justice system to hypothesis testing in statistics and the two...

ESAND ABUSES 1 Uses Hypothesis Testing Hypothesis testing is important in many different fields because it gives a scientific procedure for assessing the validity of a claim about a population. Some of the concepts in hypothesis testing are intuitive, but some are not.

A random sample of healthy volunteers were assigned to eat 3.5 ounces of dark chocolate each day for 15...
