If you wanted to create a graph for the variable age (measured in years) that showed the individual frequencies of each score and the shape of the distribution, but you were limited on space and were unable to include a frequency histogram, what graph would be most appropriate?

Use the stem-and-leaf plot below to identify the following:  **Report all answers as a whole number (e.g. 10). Maximum score: The number of people that reported they were 61 inches tall: The mode: The number of people 69 inches tall or more:  Frequency    Stem &  Leaf    10.00        6 .  0000011111    21.00        6 .  222222333333333333333    11.00        6 .  44445555555    13.00        6 .  6666677777777     9.00         6 .  888899999     4.00         7 .  0011     3.00         7 .  233 Stem width:     10.00 Each leaf:        1 case(s)

Identify the independent and dependent variables in the problem below: A teacher wanted to test the following prediction, when given a choice of books to read students will choose to read the shorter book. To test her hypothesis the teacher gave her literature class the option of reading one of two books, Alice Walker’s The Color Purple or the much longer Uncle Tom’s Cabin by Harriet Beecher Stowe. She predicted more students would choose to read The Color Purple because it is a shorter book. Consistent with her prediction 18 out of 20 students choose to read The Color Purple. The independent variable is . The dependent variable is .

Use the scores below to find the mode. 5, 6, 9, 3, 2, 8, 10, 8, 0

Construct a frequency distribution for the following scores: 5  3  3  2  4  3  4  3  3  5  4  1 Based on the frequency distribution, what is: The frequency for a score of 2 The relative frequency for a score of 2 The cumulative frequency for a score of 2 The cumulative relative frequency for the score of 2 **To receive credit for this problem you will need to show your work. At the end of the exam you will be asked to upload a picture of your work.

Use the scores below to find the mode. 5, 6, 9, 1, 5, 2, 8, 14, 1, 5

A Primary Care physician calls you because he is seeing a patient in clinic that is taking an antiepileptic drug that is causing her problems, but can’t remember the name of the drug. She is a new patient, and the MD does not have access to her medication history. The MD notes that she has problems with short term memory, and seems to have verbal fluency problems (“can’t find her words”. He wants to know if this pattern of adverse effects matches any of the AEDs. . Which of the following drugs might the patient be referring to?

If you decrease afterload, cardiac output will:

The verbal subset of the GRE has scores that are normally distributed, with a population mean of 500 and a population standard deviation of 100. Use this information to solve the following problems: 1. The percentile rank for a score of 554 2. The percentile rank for a score of 444 3. The proportion of the population with scores between 554 and 444 4. The proportion of the population with scores between 554 and 590 5. The verbal GRE score for the percentile rank of 33% **To receive credit for this problem you will need to show your work. This includes the formulas you used to calculate each value and the intermediate calculates. At the end of the exam you will be asked to upload a picture of your hand calculations.

Use the box-plot below to  identify the following values: Minimum score: The median score: The score at 25th percentile:
