A _____________________ is a tentative statement about the plausible relationship between two or more variables that is subject to empirical verification

sampling distribution of means

hypothesis

sampling error

significance test

If you have a set a significance level of .05; then your confidence level is what?

cannot determine the confidence level

90%

95%

99.95%

Which of the following is not one of the steps for hypothesis testing?

Calculating the test statistic with the summary sample statistics.

Choosing a cutoff value from your population to determine how close your sample is to the population value.

Drawing a conclusion based on the results of your test.

Deciding whether to reject or fail to reject the null hypothesis.

Many people describe hypothesis testing as counterintuitive because

we test whether something happened in order to conclude that nothing happened.

we test whether nothing happened in order to conclude that something happened.

we can only conclude that nothing happened when we are 100% sure that something did not happen.

we test whether something happened but can still conclude that nothing happened.

Given a p-value of 0.065, and using the customary α = 5%, the conclusion should be:

do not reject the null hypothesis

reject the null hypothesis

not enough information to determine

A comparison is made between two bus lines to determine if arrival times of their regular buses from Denver to Durango are off schedule by the same amount of time. For 46 randomly selected runs, bus line A was observed to be off schedule an average time of 53 minutes, with standard deviation 15 minutes. For 60 randomly selected runs, bus line B was observed to be off schedule an average of 62 minutes, with standard deviation 13 minutes. Do...

Is there a relationship between confidence intervals and two-tailed hypothesis tests? Let c be the level of confidence used to construct a confidence interval from sample data. Let α be the level of significance for a two-tailed hypothesis test. The following statement applies to hypothesis tests of the mean. For a two-tailed hypothesis test with level of significance α and null hypothesis H0: μ = k, we reject H0 whenever k falls outside the c = 1 − α confidence...

A hospital reported that the normal death rate for patients with extensive burns (more than 40% of skin area) has been significantly reduced by the use of new fluid plasma compresses. Before the new treatment, the mortality rate for extensive burn patients was about 60%. Using the new compresses, the hospital found that only 44 of 95 patients with extensive burns died. Use a 1% level of significance to test the claim that the mortality rate has dropped since using...
