1-The sum of level of significance and the level of confidence will always equal 1.

True False

2-The larger the p-value, the less likely one is to reject the null hypothesis.

True False

3-When attempting to estimate a population value, a 90% confidence interval will be narrower than a 95% confidence interval

True False

4-Even though your conclusion was to reject the null hypothesis,it is possible that it may still be true

True False

5-Ahypothesis testing question for proportions will approximate a normal distribution as long as...

both np and nq are at least 5

either np or nq is at least 5

the sample size is at least 30

the sample size is at least 5

6-When attempting to calculate an appropriate sample size in order to compute a confidence interval for the population mean, which of the following is NOT a recommended method in order to estimate the standard deviation?

Calculate the estimated range in population data divided by four

Estimate the standard deviation to be 0.50

Conduct a small pilot study

Use the standard deviation by a previous study on the same population
