A skin patch contains a new drug to help people quit smoking. A group of 75 cigarette smokers have volunteered as subjects to test the new skin patch. For one month, 40 of the volunteers receive skin patches with the new drug. The other volunteers receive skin patches with no drugs. At the end of the two months, each subject is surveyed regarding his or her current smoking habits. (Select all that apply.) a) No placebo is being used.b) Then record the smoking habits of all volunteers to see if a difference exists between the two groups.c) Then record the smoking habits of the 40 volunteers to see if a difference exists between the two groups.d) Use random selection to pick 40 volunteers for the skin patch with the drug.e) Use random selection to pick 35 volunteers for the skin patch with the drug.f) A placebo patch is used for the remaining 35 volunteers in the second group.g) Then record the smoking habits of the 35 volunteers to see if a difference exists between the two groups.

3. A mathematics placement test is given to all entering freshmen at a small college. A student who receives a grade below 35 is denied admission to the regular mathematics course and placed in a remedial class. The placement test scores and the final grades for 20 students who took the regular course were recorded as follows: Placement Test Course Grade | Placement Test | Course Grade 50 53 90 54 35 35 41 80 60 91 61 48 40 56 60 71 55 68 60 71 65 36 40 47 35 11 55 53 60 70 50 68 90 79 65 57 35 59 50 79 (a) Plot a scatter diagram. (b) Find the equation of the regression line to predict course grades from placement test scores. (c) Graph the line on the scatter diagram (d) If 60 is the minimum passing grade, below which placement test score should students in the future be denied admission to this course?

A particular country has 40 total states. If the areas of all 40 states are added and the sum is divided by 40, the result is 193,549 square kilometers. Determine whether this result is a statistic or a parameter. Choose the correct answer below. O A. The result is a statistic because it describes some characteristic of a population. O B. The result is a parameter because it describes some characteristic of a sample. O C. The result is a parameter because it describes some characteristic of a population. O D. The result is a statistic because it describes some characteristic of a sample.
