- Identify the lower class limits, upper-class limits, class width, class midpoints, and class boundaries for the given frequency distribution. Also, identify the number of individuals included in the summary. (Type integers or decimals. Do not round. Use ascending order.)

Using seven classes, create a group of frequency distributions for the data. What is the class boundaries, class limit frequency and cf?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 109 pounds and a standard deviation of 37.9pounds. Random samples of size are drawn from this population and the mean of each sample is determined.
- 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 113 pounds and a standard deviation of 37.7 pounds. Random samples of size 20 are drawn from this population and the mean of each sample is determined.What is the relative frequency for the class with lower limit 19 and rounded to 1 decimal placeWhat is the most frequent number of over-the-limit items for this data set? ans = What is the frequency of the most frequent number of over-the-limit items? ans =
- A random sample was taken of the thickness of insulation in transformer windings, and the following thicknesses in millimeters were recorded: 1. a) Make a frequency table for these data starting at lowest lower class limit of 20 and with a class width/ class size of 7. b) Determine the class marks, class boundaries, relative frequency, <CF, and >CF.Note: You can use EXCEL. 2. From question 1, Draw the frequency histogram and ogives and make a short description about the shape of distribution. 3. From the constructed frequency distribution, find the mean, median, mode, variance and standard deviation 4. From question 1: Using the frequency distribution, describe the shape in terms of its skewness and kurtosis (calculate/compute SK and K).For 60 randomly selected college students, exam score frequency distribution was obtained. Find the Coefficient of variation for the data. Class Limit Freq 5-10 6 10-15 12 15-20 18 20-25 15 25-30 9Use the Central Limit Theorem to find the mean and standard error of the mean of the sampling distribution. Then sketch a graph of the sampling distribution. The mean price of photo printers on a website is $242 with a standard deviation of $69. Random samples of size 32 are drawn from this population and the mean of each sample is determined. The mean of the distribution of sample means is enter your response here.
