For the scenario below, answer the following: Is the situation Binomial or Hypergeometric? Referring to your criteria, how do you know which it is? Change the situation so that it could be calculated using the other distribution. (For example, if it is Binomial, change to Hypergeometric) Scenario 1: A study reports that 5% of adults are afraid to be home alone at night. If 20 people are randomly selected, what is the probability at least 3 of them are afraid to be home alone at night?

Suppose that you would like to determine if the use of the newest Sweeney education intervention will improve students understanding of statistics better than the use of no intervention. In order to do this, you select two groups of students at random from students who need to take Statistics: a group given the intervention and another group that is given the standard statistics class. At the end of the course, the students were given an exam and the exam scores were compared. Group 1: Students given the interventionGroup 2: Students in the standard Statistics class Use this information to answer the following questions:a. What test should you run and why?b. What is the null hypothesis? What is the alternative hypothesis?c. What requirements would have to be met to insure that you could run the test?
Anyone who has been outdoors on a summer evening has probably heard crickets. Did you know that it is possible to use the cricket as a thermometer? Crickets tend to chirp more frequently as temperatures increase. This phenomenon was studied in detail by George W. Pierce, a physics professor at Harvard. In the following data, x is a random variable representing chirps per second and y is a random variable representing temperature (°F). x 19.8 15.3 20.4 18.1 16.2 15.5 14.7 17.1 y 89.4 73.2 95.3 86.1 78.8 75.2 69.7 82.0 x 15.4 16.2 15.0 17.2 16.0 17.0 14.4 y 69.4 83.3 79.6 82.6 80.6 83.5 76.3 (b) Verify the given sums Σx, Σy, Σx2, Σy2, Σxy, and the value of the sample correlation coefficient r.

A researcher selects a sample of 6 men and 11 women. She asks participants to rate the likelihood they would do female-stereotyped jobs (such as nursing or school teaching) on a scale from 1 = not likely at all to 5 = very likely. Men indicated that they would be less likely to do these jobs (M = 2.1) compared with women (M = 4.3). What is the weighted mean for the combined sample of 17 total participants? O O 2.1 4.3 3.2 3.5
