- Construct a frequency table. Consider the scores of 50 Grade 12 students in Physics exam. Construct a frequency distribution and compute the indicated positions using Table 1 and Table 2. The lowest value is the first lower class limit of Table 2.Number of Classes k: 2k ≥ n k=_____ Class interval or width C= Range/K=________a. The distance people travel to work on a typical day - The horizontal axis is the distance traveled in a person's daily commute. The vertical axis is frequency (number of people with that distance for their daily commute). Shape of distribution: symmetric skewed right skewed left uniform Justification:The distance people travel to work on a typical day - The horizontal axis is the distance traveled in a person's daily commute. The vertical axis is frequency (number of people with that distance for their daily commute). Shape of distribution: uniform symmetric skewed left skewed right
- USING 8 AS THE LOWER LIMIT OF THE CLASS AND WITH A WIDTH OF 1 UNIT, CONVERT IT TO FREQUENCY DISTRIBUTIONConstruct a grouped frequency distribution table for this data set. You want 10 classes with a “nice” class width. Your classes should be labeled using interval notation. Each class contains its lower class limit, and the lower class limits should all be multiples of the class width. In that the data appears to be discrete, use a closed-interval to label each class.make frequency distribution table where there is the class interval and the frequency. use appropriate solution for class interval. use Sturges formula for number of classes and range over the no. of classes for the class size. this will lead to creating class interval.

Then sketch a graph of the sampling distribution. The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 100 pounds and a standard deviation of 38.5 pounds. Random samples of size 18 are drawn from this population and the mean of each sample is determined. μx=nothing
- Describing the sampling distribution of the sample means from an infinite population. The best way to solve this is to use the CENTRAL LIMIT THEOREM.Use the central limit theorem to find the mean and standard error of the mean of the indicated sampling distribution. Then sketch a graph of the sampling distribution. The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 100 pounds and a standard deviation of 38.6 pounds. Random samples of size 20 are drawn from this population and the mean of each sample is determined. ux= o-x= graph=The temperature in oF in Yosemite National Park, California in random 20 days were recorded in the following stem-and-leaf plot.
