## Grade Distribution Analysis: 9 AM Class vs 10 AM Class### Frequency Distribution TableTwo classes took the same examination, and their grades are recorded in the table below. This table gives the frequency distribution of grades in each class. The task is to find the relative frequency distribution and describe the grade distributions' differences.#### Number of Students| Grade | 9 AM Class | 10 AM Class ||-------|------------|-------------|| F | 9 | 13 || D | 16 | 19 || C | 22 | 10 || B | 10 | 21 || A | 6 | 20 |### Relative Frequency DistributionConstruct a relative frequency distribution of the data. Relative frequency is calculated by dividing the frequency of each grade by the total number of students in the class. Round to the nearest thousandth as needed.#### Relative Frequency Table| Grade | Relative Frequency 9 AM Class | Relative Frequency 10 AM Class ||-------|-------------------------------|--------------------------------|| F | | || D | | || C | | || B | | || A | | |### Instructions:1. Calculate the total number of students for each class.2. Compute the relative frequency for each grade by dividing the number of students with a specific grade by the total number of students in that class.3. Fill in the relative frequency values in the corresponding table.This exercise helps in understanding how grade distributions vary between different classes and how to interpret these distributions using relative frequencies.

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?

Nicole has a popular blog about cooking and nutrition and regularly posts articles and videos. She has collected data about the length of time that viewers spent watching two of her recent videos. For each video, she recorded the amount of time (in minutes) that each of 102 viewers spent watching it. The histograms below show the distributions of the two data sets. Each histogram shows time (in minutes) on the horizontal axis and the number of viewers on the vertical axis. The means and standard deviations for the data sets are also given.
