Which of the following is the best interpretation of theprobability that the number landing face up will be less than 3 ?(A) For many rolls of the die, the long-run relative frequency of a number less than 3 landing face up is 1/3.(B) For many rolls of the die, the long-run relative frequency of a number less than 3 landing face up is 1/2.(C) For many rolls of the die, the long-run relative frequency of a number less than 3 landing face up is 2/3.(D) For three rolls of the die, a number less than 3 will land face up one time.(E) It will take three rolls of the die before a number less than 3 lands face up for the first time.Use a 0.01significance level to test the reasonable claim that births occur with equal frequency on the different days of the week.

- A teacher wanted to test that if telling students that a test would be curved to the highest grade would help them perform better on quizzes. She gave quizzes to two groups of 5 students each and told one that there would be a curve and the other group was told there would be no curve given. Following are the scores on the quizzes for the two groups: Yes curve: 75, 80, 78, 87, 90No curve: 76, 83, 72, 80, 70 Run an independent t test on the data and report the test results using an alpha level of .05.

Each participant attempted 20 putts. The researcher wrote, "A downward facing projector displayed displayed a ring of 11 small (3.8 centimeters in diameter) or 5 large (28 centimeters) circles around each hole to create an Ebbinghaus illusion." For each illusion, participants attempted 10 putts from a distance of 3.5 meters, and we recorded how many putts dropped into the hole" (Witt et al, 2012, p. 397). The researchers hypothesized that participants would make more putts when the hole was surrounded by smaller circles (making the golf hole appear larger) than when it was surrounded by larger circles (making the golf hole appear smaller. How would classify the design of the study? a. This was a correlation study b. This was an experiment using a between-groups research design c. This was an experiment using a within-groups research design d. This was an outlier analysis
