**Question:**Which of the following statement(s) is/are true?- [ ] If the (α) is more than the p-value, there is evidence to reject the null hypothesis.- [ ] If the (α) is less than the p-value, there is evidence to reject the null hypothesis.- [ ] The significance level, (α), can be described as the amount of risk that a researcher is willing to take when incorrectly rejecting the null hypothesis.- [ ] Power describes the ability to detect an effect if an effect exists.- [ ] The test statistic is the z-score the significance level, (α), is separated from the rest of the normal curve.- [ ] The test statistic is the z-score which marks where the sample’s z-score is located on the normal curve.

If the p-value is greater than alpha, you accept the null hypothesis. If p-value is less than alpha,…

A researcher is designing an experiment. Ultimately, she is hoping to reject her null hypothesis (i.e., show that the results of her experiment are statistically significant). What type of p-value would she want to obtain? 1. A large p-value. 2. A small p-value. 3. The size of a p-value has no impact on statistical significance.

A social psychologist is interested in finding out whether people who self-identify as shy are more likely to attend certain types of colleges. He surveys college-bound graduating seniors and asks them what type of college they plan to attend and whether or not they consider themselves shy. The following frequency distribution table summarizes the responses to the two survey questions. Not Shy Shy Total Liberal Arts College 73 35 108 Four-Year University 155 24 179 Community or Junior College 82 7 89 College Type Fill in the three missing values in the frequency distribution table. Agricultural, Technical, or Specialized College 582 239 Other 18 41 59 Total 910 The following questions walk you through the steps of a test of the null hypothesis that a student's choice of college type is independent of whether he self-identifies as shy. If a student's choice of college type is independent of whether he self-identifies as shy, then the expected frequency for the Shy/Agricultural,…
