Question
For the project you will have to: Collect and organize a sample of 30 items of data from a source you find relevant. Some examples: Sports (top HR hitters, rushing leaders, point scorers, etc.) Weather (average daily temperature for a month, max hurricane wind speed, etc.) Business (top grossing movies, highest paid athlete's, record sales, etc.) Demographics (age, height, weight, etc.) Construct a grouped frequency distribution (show frequency, cumulative frequency and relative frequency). Find the mean, median, mode and range for your date. Find the variance, standard deviation for your data (assume your data represent a population). Find the five number summary and determine (mathematically) if there are any outliers. Find the z-score that represents the top 20% Take a random sample of 7 values from your population. What is the probability of obtaining that value or higher.Explanation / Answer
Mean = 148.2
Meadian = Average of 15th and 16th observation = 149
Mode = Highest frequency = 140
Range = Maximum observation - minimum observation = 160-139 = 21
5) 5 number summary
Minimum = 139
Q1 = Median of the first half observation = median of the first 15th observations = 8th observation = 142
Q2 = Meadian of the data = 149
Q3 = Median of the last 15 observation = 22nd observation = 152
Maximum = 160
