You are a student pursuing an introductory Statistics course. The researcher has asked that you assist him in summarizing, analyzing and interpreting the information gathered, by answering the questions below.

QUESTION 1

((

(a) (i) Identify the population of interest for this scenario.                                                                                                                                    

((

(ii) Identify the sampling technique used by the researcher.                                                                                                                          

(iii) State one advantage and one disadvantage of the sampling technique described in the

      Given scenario.

Students enrolled in an introductory statistics course at a university were asked to take a survey that indicated whether the student’s learning style was more visual or verbal. Each student received a numerical score ranging from -11 to +11. Negative scores indicated a visual learner, and positive scores indicated a verbal learner. The closer the score was to -11 or +11, the stronger the student’s inclination toward that learning style. A score of 0 would indicate neutrality between visual or...

COIN TOSSES In a large class of introductory Statistics students, the professor has each student toss a coin 16 times and calculate the proportion of his or her tosses that were heads. The students then report their results, and the professor plots a histogram of these several proportions. What shape would you expect this histogram to be? Why? Where do you expect the histogram to be centred? How much variability would you expect among these proportions? Explain why a Normal...

When an introductory statistics course has been taught live, the average final numerical grade has historically been 71.6% with a standard deviation of 8.8%. Forty students were selected at random to take a new online version of the same course, and the average final numerical grade for these students was found to be 69.2%. Assume that the grades for the online students are normally distributed and that the population standard deviation is still 8.8%. In parts (a) and (b), use...

A student survey was completed by 446 students in introductory statistics courses at a large university in the fall of 2003. Students were asked to pick their favorite color from black, blue, green, orange, pink, purple, red, yellow. (a) If colors were equally popular, what proportion of students would choose each color? (Round your answer to three decimal places.) (b) We might well suspect that the color yellow will be less popular than others. Using software to access the survey...
