**Question**: What statement below is consistent with making a Type II error?- ☐ concluding that a treatment has an effect when it really does- ☐ concluding that a treatment has no effect when it really has no effect- ☐ concluding that a treatment has no effect when it really does- ☐ concluding that a treatment has an effect when it really has no effect**Explanation for Educational Website**:A Type II error occurs when we fail to reject a false null hypothesis. In simpler terms, it happens when a test concludes that there is no effect or no difference when, in fact, there is. This type of error is often due to insufficient power in a study to detect an effect that actually exists. In the options provided, the statement that matches the description of a Type II error is:- "concluding that a treatment has no effect when it really does"

Type II error is the probability of fail to reject the null hypothesis when alternative hypothesis…

9. A researcher finds that for female applicants, the likelihood of being hired for a job increases as their work experience increases. However, for male applicants, the likelihood of being hired decreases as their work experience increases. This finding would suggestgender and work experience have no effect on likelihood of being hired for a job. a main effect of work experience (little or a lot). an interaction between gender and work experience. a main effect of gender (male or female).
A psychologist finds that fidgety patients tap their fingers on average 500 times during a 2 hour period. You wish to test this claim for the same patients, but in a room decorated with soothing colors and soft lighting. You believe that a warmly decorated room may alter the fidgeting behavior, causing subjects to tap their fingers less than they do under normal conditions. A random sample of 400 patients has a mean of 420 taps and a standard error of 30 taps in a 2 hour period. Find the margin of error for the average tapping of fingers during a 2 hour period.
Dr. Mackintosh believes a new olfactory therapy would be more successful in promoting weight loss among obese patients. His patients are first weighed and then randomly assigned to olfactory therapy, dance therapy, or a control condition. At the end of the three weeks, the amount of weight lost is recorded. The results indicate no significant difference in the amount of weight lost between the three conditions. If true differences existed between the conditions, but they were not detected, what kind of error occurred?
A clinical trial is run to investigate the effectiveness of an experimental drug in reducing preterm delivery to a drug considered standard care and to a placebo. Pregnant women are enrolled and randomly assigned to receive either the experimental drug, the standard drug or a placebo. Women are followed through delivery and classified as delivering preterm (< 37 weeks) or not. The data are shown below. Preterm Delivery Experimental Drug Standard Drug Placebo Yes 15 23 40 No 83 79 67 Is there a statistically significant difference in the proportions of women delivering preterm among the three treatment groups? Run the test at a 5% level of significance.
The personality characteristics of business leaders (e.g., CEOS) are related to the operations of the businesses that they lead (Oreg & Berson, 2018). Traits like openness to experience are related to positive financial outcomes and other traits are related to negative financial outcomes for their businesses. Suppose that a board of directors is interested in evaluating the personality of their leadership. Among a sample of n = 16 managers, the sample mean of the openness to experiences dimension of personality was M = 4.50. Assuming that u = 4.24 and o = 1.05 (Cobb-Clark & Schurer, 2012), use a two-tailed hypothesis test with a = .05 to test the hypothesis that this company's business leaders' openness to experience is different from the population.
