Mars, Inc. states that 16% of all milk chocolate M&M’S® produced are green. A group of students took the following samples from a bowl of 500 mixed up M&M’S®. (see attached) What information do we need in order to answer our question or investigate the claim that 16% of milk chocolate M&M’S® produced by Mars, Inc. are green? How can we use the samples of M&M’S® to obtain this information? What value is at the center of the dot plot constructed by using one sample per group? Is it a coincidence that the value is close to/far from the 16% claimed by Mars, Incorporated? Mars, Inc. claimed that 16% of milk chocolate M&M’S® produced are green. Does the information on the dot plot seem to support this claim? Why or why not?

2. A researcher measures the relationship between education (in years) and investment gains (in thousands of dollars). Answer the following questions based on the results provided. SP = 16.25.a. Create a scatter plot of the datab. Calculate r and r2c. Report results in APA style.d. What do results mean
The following pairs of observations tell the result of the laboratory experiment yand the temperature x at which the laboratory experiment was carried out. Observations as following: i xi yi i xi yi1 100 45 7 150 692 110 51 8 160 743 120 54 9 170 784 125 53 10 180 865 130 59 11 190 896 140 63 12 200 94 So the question regarding the table above would be (a) Draw a scatter diagram of the table. (b) Visually draw a line that fits the data (in table) as well as possible.(c) Fit a linear model to the data, i.e. estimate the PNS estimates of the regression line. Compare the regression line you get with the one you drew in (b) (ie compare the slopes/intercepts).(d) Predict the result of the laboratory experiment when the experiment is performed at a temperature of 185. R software or other software for linear regressions should not be used to solve this.
