The table shows a stem-and-leaf diagram for the test scores of students in a Liberal Arts Math course.  How many scores are recorded in this stem and leaf plot? [one] What is the highest score in the plot? [two] How many students earned the highest score? [three]

The following frequency distribution shows the length of several observed conversations.       What is the upper class boundary for the range of 10-14? [upper] What is the class width? [width]

Multiple choice questions on a test each have 4 possible answers, one of which is correct.  Assume that you guess the answers to 3 such questions. Use the multiplication rule to find the probability that the first two guesses are wrong and the third guess is correct.  That is, find P(WWC) where W denotes a wrong answer and C denotes a correct answer.  Round your answer to 4 decimal places. [WWC] On your scratch paper, make a complete list of the different possible arrangements of 2 wrong a 1 correct answer.  What is the probability of each combination?  Round to 4 decimal places. [comb] What is the probability of getting exactly 1 correct answer when 3 guesses are made?  Round to 4 decimal places. [one]

  What is the 5 number summary for the data set above? [min],  [q1],  [median],  [q3], [max]    

The size of the last 12 graduating classes of a certain high school are given below. 227 239 215 219 221 233 229 233 235 228 245 231 Mean:  [mean] Median:  [median] Standard Deviation:  [std] Round each answer to the nearest tenth as needed.

In a sample of 1,047 randomly selected adults, 38% said they did not intend to vote in the next election. How many adults in the survey said they did not intend to vote? [one]   In one of Mendel’s experiments with green and yellow peas, 123 out of 515 peas were yellow. What percentage of the peas were yellow?  Round to the nearest tenth of a percent. [two]%   Last year an airline reported that a specific flight was delayed 47 times. This year they reported a 13% reduction in delays for the same flight.  How many times was the flight late this year? [three]

Does the table below represent a valid probability distribution?

The weights (in pounds) of 30 newborn babies are listed below. Find 

Assume that a researcher randomly selects 14 newborn babies and counts the number of girls selected, . The probabilities corresponding to the 15 possible values of are summarized in the given table. Answer the question using the table.                       Probabilities of Girls Find the probability of exactly 5 girls. [five] Find the probability of 9 or more girls. [9ormore]

For the following binomial distribution, give the minimum usual value and the maximum usual value.  Round your answers to two decimal places.                   n = 93, p = 0.24 minimum usual value [min] maximum usual value [max]
