When you open a bag of M&M's you expect to see 30% brown, 20% yellow, 20% red, 10% orange, 10% green and 10% blue.  You look in your bag of 150 M&M;s and find the following results.  Is there evidence to say your bag has differing results at α=.05α=.05? Brown 49 Yellow 40 Red 40 Orange 10 Green 5 Blue 6 The Pvalue is P =  .  (4decimals) There is  to say the results vary.

Katie is interested if an association exists between age and sleep habits. She selects a random sample of 68 adults in three age groups and determines whether they sleep less than 7 hours, between 7 and 8 hours, or more than 8 hours each night. She would like to determine if there is convincing evidence of an association. Let  = 0.05. What are the hypotheses for this test? H0: There is an association between age and sleep habits.Ha: There is no association between age and sleep habits. H0: There is no association between age and sleep habits.Ha: There is an association between age and sleep habits. H0: There is no difference in the distribution of age and sleep habits.Ha: There is a difference in the distribution of age and sleep habits. H0: There is a difference in the distribution of age and sleep habits.Ha: There is no difference in the distribution of age and sleep habits.

In a study of exhaust emissions from school buses, the pollution intake by passengers was determined for a sample of nine school buses used in the Southern California Air Basin. The pollution intake is the amount of exhaust emissions, in grams per person, that would be inhaled while traveling on the bus during its usual 18-mile trip on congested freeways from South Central LA to a magnet school in West LA. Here are the amounts for the nine buses when driven with the windows open. 1.17     0.33    0.40     0.33     1.32     0.38     0.25     0.40     0.35   (a) Consider making a stemplot. Are there outliers or strong skewness that would preclude use of the t procedures? Which is correct? A. The sample is small and the stemplot is right skewed with possible outliers, so use of t procedures is not appropriate. b. The distribution is symmetric so use of t procedures is appropriate.    c. The sample is small and the stemplot is left skewed with possible outliers, so use of t procedures is…

b) Calculate the fitness of a population with allele frequency x = 0.4. W = Give your answer rounded to 2 decimal places. Find the allele frequency, x, of a population with fitness 0.2. X =

Do you prefer paintings in which the people are fully clothed? This question was asked by a professional survey group on behalf of a national arts organization. A random sample of n1 = 58 people who are conservative voters showed that r1 = 45 said yes. Another random sample of n2 = 64 people who are liberal voters showed that r2 = 39 said yes. Does this indicate that the population proportion of conservative voters who prefer art with fully clothed people is higher? Use α = 0.05. (a) What is the level of significance?State the null and alternate hypotheses. H0: p1 = p2; H1: p1 ≠ p2H0: p1 > p2; H1: p1 = p2    H0: p1 = p2; H1: p1 < p2H0: p1 = p2; H1: p1 > p2 (b) What sampling distribution will you use? What assumptions are you making? The Student's t. We assume the population distributions are approximately normal.The standard normal. We assume the population distributions are approximately normal.    The standard normal. The number of trials is sufficiently large.The Student's…

A researcher developing scanners to search for hidden weapons at airports has concluded that a new scanner is significantly better than the current scanner. He made his decision based on a test using a = 0.05. Would he have made the same decision at a = 0.20? How about α = 0.01? Explain. Select the statement relating decision making to values of a. O A. His decision would have been the same for a = 0.01 but may have been different for a = 0.20. O B. His decision would have been the same for α = 0.20 but may have been different for α = 0.01. O C. His decision may have been different for both α = 0.01 and α = 0.20. O D. His decision would have been the same for both α = 0.01 and α=0.20.
