Use the given frequency distribution to find the a class width. Write the word or phrase that best completes each statement or answers the question. Use the maximum and minimum data entries and the number of classes to find the class width, the lower class limits, and the upper class limits. Provide an appropriate response. Use the relative frequency histogram to a identify the class with the greatest, and the class with the least, relative frequency.

The number of accidents dropped in year 3 after a new speed limit was imposed.

Does the graph distort the data? How would you redesign the graph to be less misleading? A skewed right B uniform C skewed left D symmetric 13 Full file at https: A skewed right B symmetric C skewed left D uniform 61 Find the mean, median, and mode of the data.

Describe the shape of the histogram as symmetric, uniform, skewed left, or skewed right. California Pick Three Lottery 63 8 6 7 6 0 9 1 7 8 4 1 5 7 5 9 7 5 3 9 9 8 8 3 9 8 8 9 0 2 7 A symmetric B skewed left C skewed right D uniform 14 Full file at https: Find the mean speed.

Find the mean 71 score. Find the mean and median number of runs batted in. Round the mean to the nearest whole number. Find the mean and median number of home runs. Which measure of central tendency- the mean or the median - best represents the data? Explain your reasoning. Find the median speed. Find the median 75 score. Find the mode speed.

Find the mode 77 score.

Find the mean and median winnings. Round to the nearest dollar. Which measure - the mean or the median- best represents the data? The student's final exam score is 88 and homework 79 score is What is the student's mean score in the class?

Grades are weighted 80 according to credit hours. If a student receives an A in a four- credit class, a D in a two- credit class, a B in a three- credit class and a C in a three- credit class, what is the student's grade point average?

Is 86 the mean a good representation of the center of data? If not, why? Is 87 the mode a good representation of the center of data? Find 89 the midrange for this data. A 6 minutes B 7 minutes C 10 minutes D 2 minutes 90 The cost of five homes in a certain area is given. A mode B median C mean D midrange 91 The cost of five homes in a certain area is given. Find the range of the data set. Find the sample standard deviation of the data set. Find the population standard deviation and the population variance.

The data is listed below. Compute the range, standard deviation and variance of the data.

B Data sets i and iii have the same range. C Data sets i and ii have the same standard deviation. D Data set i has the smallest standard deviation. Without calculating, determine which data set has the greatest sample standard deviation and which has the least sample standard deviation.

There are two types available. Type A has a mean life of five years and a standard deviation of one year. Type B has a mean life of five years and a standard deviation of one month. Both batteries cost the same. Which one should you download if you are concerned that your car will always start?

Which player is more consistent? Sammy Sosa 0. You must download fluorescent light bulbs for the classrooms. Use the Empirical Rule to find the percentage of adults with scores between 70 and Assume the data set has a bell- shaped distribution. Use the Empirical Rule to find the percentage of scores that lie between 60 and Use the Empirical Rule to find the percentage of scores between 53 and Between what two values do about Use the Empirical Rule to determine the percentage of women whose pregnancies are between and days.

Use the Empirical Rule to determine what percent of the scores lie between and The monthly rents for eight more studio apartments in the city are listed. Using the sample statistics above, determine which of the data values are unusual. Are any of the data values very unusual?

There are no values that are very unusual because no value is more than 4 standard deviations from the mean. Does Chebyshev's Theorem say about the percentage of women with heights between Interpret the results.

Use the grouped data formulas to find the indicated mean or standard deviation. Approximate the sample mean. The results are summarized in the frequency distribution below.

Each student is asked how many hours he or she spent on the Internet during the previous week. The results are shown in the histogram. Estimate the sample mean. Estimate the sample standard deviation. The data set: The systolic blood pressures of 20 randomly selected patients at a blood bank. B The standard deviation will be multiplied by the constant k. Compute the coefficient of variation. Find the coefficient of variation for each of the two sets of data, then compare the variation.

Round results to one decimal place. Men aged 20 - B Men aged 20 - C Men aged 20 - D Men aged 20 - On Monday they try the first system which is based on an automated menu system. On Tuesday they try the second system in which each caller is immediately connected with a live agent. A quality control manager selects a sample of seven calls each day.
