The distribution of the tuitions, fees, and room and board charges of a random sample of public 4-year degree-granting postsecondary institutions is shown in the pie chart. Make a frequency distribution for the data. Then use the table to estimate the sample mean and the sample standard deviation of the data set Use $26249.50 as the midpoint for "$25,000 or more." Complete the frequency distribution for the data (Type integers or decimals. Do not round.) Class X $15,000-$17,499 $17,500-$19,999 $20,000-$22,499 $22,500-$24,999 $25,000 or more $15,000-$17,499 11 $17,500-$19.999 10 $20,000-$22.499 18 $22.500-$24,999 13 $25,000 or more 7

You want to examine the relationship between dropping out of high school and delinquency. You have a random sample of 11 students. You have the number of delinquent offenses that each student reported committing in the year before and after dropping out of school. The following table shows the data. Student Before dropping out After dropping out 1 5 7 2 9 5 3 2 3 4 7 7 5 8 11 6 11 13 7 8 4 8 8 10 9 5 7 10 2 1 11 9 3 From performing a hypothesis test to determine if the mean number of delinquent differs after dropping out, what is the obtained t?

From the states data set, get the descriptive statistics for the violent crime rate. For this assignment, you will need the mean, standard deviation, five-number summary (minimum, 25th percentile, median, 75th percentile, maximum), and interquartile range. Submit all answers as whole numbers--no decimal points. If you have to calculate the interquartile range by hand, you may calculate it using whole numbers as the 25th and 75 percentile. How would i calculate this?

The distribution of the number of hours that a random sample of people spend doing chores per week is shown in the pie chart. Use 32 as the midpoint for "30+ hours." Make a frequency distribution for the data. Then use the table to estimate the sample mean and the sample standard deviation of the data set. Click the icon to view the pie chart. First construct the frequency distribution. Class Frequency, f 0-4 5-9 10-14 15-19 20-24 25-29 30+ Find an approximation for the sample mean. X= (Type an integer or decimal rounded to the nearest tenth as needed.) Find an approximation for the sample standard deviation. S= (Type an integer or decimal rounded to the nearest tenth as needed.) Weekly Chore Hours 0-4 hours (3 people) 5-9 hours (14 people) 10-14 hours (21 people) 15-19 hours (18 people) 20-24 hours (17 people) 25-29 hours (11 people) 30+ hours (7 people) - X -

The accompanying frequency distribution represents the square footage of a random sample of 500 houses that are owner occupied year round. Approximate the mean and standard deviation square footage. Click the icon to view the data table. The mean square footage is x=. (Round to the nearest integer as needed.)

If you have a stem and leaf plot with numbers: 57,61,70,72,72,72,74,80,82,82,86,89,94,95,95,99,100,116,116,126 how do you find the varience and the standard deviation?

The first step in finding the interquartile range involves calculating the ____ of the data set. a. mean b. median c. standard deviation d. range
