Question

In a hypothesis testing problem:

Question 6 options:

a. the null hypothesis will not be rejected unless the data are not unusual (given that the hypothesis is true).

b. the null hypothesis will not be rejected unless the p-value indicates the data are very unusual (given that the hypothesis is true).

c. the null hypothesis will not be rejected only if the probability of observing the data provide convincing evidence that it is true.

d. the null hypothesis is also called the research hypothesis; the alternative hypothesis often represents the status quo.

e. the null hypothesis is the hypothesis that we would like to prove; the alternative hypothesis is also called the research hypothesis.

The risk of a Type II error is directly controlled in a hypothesis test by establishing a specific significance level.

Question 8 options:

Which of the following is not true about the null hypothesis:

Question 9 options:

All of the above are true

Acceptance sampling (defined):

Question 11 options:

Question 8 options:

True

Which of the following is not true about the null hypothesis:

Question 9 options:

a) Usually the null hypothesis is a statement of "no effect" or "no difference" b) Either the null hypothesis is rejected or accepted c) The null hypothesis is contrasted with the alternative hypothesis, denoted by Ha or H1 d) A null hypothesis must be sufficiently specific to define the sampling distribution for the sampling statistic which is used to calculate the p-value e)

All of the above are true

Acceptance sampling (defined):

Question 11 options:

a) Acceptance sampling means the alternate hypothesis, Ha, is accepted b) Acceptance sampling is "the middle of the road" approach between no inspection and 100% inspection c) Acceptance sampling is failing to reject the null hypothesis, d) Acceptance sampling is using confidence levels to either accept or reject the null hypothesis, H0 e) None of the above is acceptance sampling

False

Explanation / Answer

6.e. the null hypothesis is the hypothesis that we would like to prove; the alternative hypothesis is also called the research hypothesis.

The null hypothesis is contrasted with the alternative hypothesis, denoted by Ha or H1

9.c)

The null hypothesis is contrasted with the alternative hypothesis, denoted by Ha or H1

11 d) Acceptance sampling is using confidence levels to either accept or reject the null hypothesis, H0
