- What is a sample space?Construct a frequency distribution having 5 classes.In order to compare the real estate markets in Pittsburgh and Philadelphia, a realtor selected a random sample of 150 homes in the Pittsburgh area and 100 homes in the Philadelphia area. Shown below are dotplots showing the distribution of home price for the homes in these two cities.
- The age of retirement for professional sports players (from different sports) has been summarized in a contingency table that provides a joint frequency distribution.Section of an oil field has been divided into 48 equal sub-areas. Counting the oil wells in the 48 sub-areas gives the following frequency distribution : Number of 0 1 2 3 4 5 6 7oil wellsNumber of 5 10 11 10 6 4 0 2sub-areasIs there any evidence from these data that the oil wells are not distributed randomly throughout the section of the oil field?A researcher has obtained the number of hours worked per week during the summer for a sample of 15 students.[40, 25, 35, 30, 20, 40, 30, 20, 40, 10, 30, 20, 10, 5, 20]Using this data set and Excel Template 2 (available in Canvas), compute the following:a.

- Please answer all sub-parts According to the manufacturer of M&Ms, 12% of peanut M&Ms in a bag should be brown, 15% yellow, 12% red, 23% blue, 23% orange, and 15% green. A student randomly selects a bag of peanut M&Ms. For the 400 M&Ms in the bag, the the number of M&Ms that were of each color is in the table below. At the ? = 0.05 level, does the data support the manufacturer's claim for the distribution of colors of peanut M&Ms? (Note: We did not give the Expected Counts, you will need to compute them yourself.) Color Frequency Brown 53 Yellow 66 Red 38 Blue 96 Orange 88 Green 59 Complete the hypothesis test: a) State the null and alternative hypotheses: H0 and H1 b) Compute the ?2 statistic c) Give the critical ?2 value (from Table VIII). d) State the conclusiona.) If samples of size 3 are selected, how many different samples are possible? b.) List the Various samples and compute the mean of each c.) Develop a sampling distribution of the means. d.) Draw graphs to compare the variability of the sampling distribution of the mean with that of the population.Identify and sketch three distribution shapes that are symmetric.
