The Daily News reported that the color distribution for plain M&M’s
was: 40% brown, 20% yellow, 20% orange, 10% green, and 10% tan. Each piece of candy in a random sample of 100 plain M&M’s was classified according to color, and the results are listed below. Use a 0.05 significance level to test the claim that the published color distribution is correct.
Color——-Brown—–Yellow—–Orange—–Green—–Tan
Number—-42———–18———15————7———–18
(a) What is the appropriate hypothesis test (z-test for sample proportion, t-test for sample mean, chisquare goodness of fit test, F-test for ANOVA) Why?
(b) Identify the null hypothesis and the alternative hypothesis
(c) How do you determine the test statistic?
(d) How do you determine the P-value?
(e) Compare p-value and significance level α. What decision should be made regarding the null hypothesis (e.g., reject or fail to reject) and why?
(f) Is there sufficient evidence to support the claim that the published color distribution is correct? Why?

An instructor believes that the average quiz score is a good predictor
of final exam score. A random sample of 10 students produced the following data where x is the average quiz score and y is the final exam score.
x 80 95 50 60 100 55 85 70 75 85
y 70 96 50 63 96 60 83 60 77 87
(a) Find an equation of the least squares regression line and show how. Round the slope and y-intercept value to two decimal places.
(b) Based on the equation from part (a), what is the predicted final exam score if the average quiz score is 65?
(c) Based on the equation from part (a), what is the predicted final exam score if the average quiz score is 40?
(d) Which predicted final exam score that you calculated for (b) and (c) do you think is closer to the true final exam score and why?
