The number of hospital beds in a sample of 20 hospitals is shown below. Construct a frequency distribution and a frequency histogram for the data set using 5 classes. Describe the shape of the histogram as​ symmetric, uniform, negatively​ skewed, positively​ skewed, or none of these. 167 158 127 133 182 161 172 223 149 141   196 204 154 255 266 244 307 137 203 177

Complete the frequency table for this data. 91.3.96.7,91.4, 88.4.92.8, 96.7, 82.4, 87.3, 85.7, 95.2, 81.2, 93.2, 85.9, 84.9, 85.8, 83.5, 88.6, 82. I Determine the frequency of each class in the table shown. Grades of Students in Physics Class Frequency 78.0-81.9 82.0-85.9 86.0-89.9 90.0-93.9 94.0-97.9

The data represent the time, in minutes, spent reading a political blog in a day. Construct a frequency distribution using 5 classes. In the table, include the midpoints, relative frequencies, and cumulative frequencies. Which class has the greatest frequency and which has the least frequency? 7 12 15 6 0 6 3 3 15 14 13 6 19 13 15 8 15 11 8 9

This is for a review ! Thank you for your help

Use the frequency histogram to complete the following parts. (a) Determine the number of classes. (b) Estimate the greatest and least frequencies. (c) Determine the class width. (d) Describe any patterns with the data. Frequency Employee Salaries 300- 200- 100- ☑ 0 32 37 42 47 52 57 62 Salary (in thousands of dollars) (a) There are classes. (Type a whole number.) (b) The least frequency is about (Round to the nearest whole number as needed.) The greatest frequency is about (Round to the nearest whole number as needed.) (c) The class width is (Type an integer or a decimal. Do not round.) (d) What pattern does the histogram show? A. About half of the employees' salaries are between $50,000 and $59,000. B. About half of the employees' salaries are between $40,000 and $49,000. C. Less than half of the employees make between $35,000 and $59,000. D. Most employees make less than $34,000 or more than $60,000.

Question Data showing the population by state in millions of people follow (The World Almanac, 2012). The dataset in Excel file 2012Population.xlsx.a. Develop a frequency distribution, a percent frequency distribution, and a histogram. Use a class width of 2.5 million. b. Does there appear to be any skewness in the distribution? Explain. c. What observations can you make about the population of the 50 states?

Please do not give solution in image format thanku A car salesman collected data on how many cars were sold at a dealership per day for two weeks. The results were as follows: 6, 7, 4, 3, 1, 2, 6, 6, 6, 7, 4, 4. Make a frequency table and then make a histogram based on that frequency table. What is the shape of the distribution? O Skewed to the right O Skewed to the left O Bimodal O Symmetrical

Find the median and mode of the data set: 15, 18, 19, 16, 21, 25, 17, 21, 20, 14 Select one: O a. Median = 19, Mode = 18 O b. Median = 18.5, Mode = 19 O c. Median = 18, Mode = 21 %3D O d. Median = 18.5, Mode = 21

You obtain the following (sample) data: 56, 77, 79, 68, 69, 68, 68, 68, 50, 55, 55, 78, 72. (a) Arrange the data in a Frequency Distribution with the following classes: 50-59 60-69 70-79 (b) Draw the corresponding Histogram. (c) Draw the corresponding Stem-and-Leaf Diagram. (d) Find the Mean, Median, Mode, Midrange, Range, and Standard Deviation.

A student was interested in the cigarette-smoking habits of college students and collected data from an unbiased random sample of students. The data are summarized in the following table. Males who smoke Males who do not smoke Females who smoke Females who do not smoke What type of chart best represents the relative class frequencies? Multiple Choice Pie chart Box plot Frequency polygon 10 40 15 60 Scatterplot
