Q. For a physics course containing 10 students, the maximum point total for the quarter was 200. The point totals for the 10 students are given in the stemplot below.
A. Since there are 7 stems, the median must be contained in the fourth smallest stem and be between 140 and 150.
B. We can compute the mean number of points for the 10 students from the information in the stemplot.
C. Because of the small sample size, it would be impossible to split the stems in this stemplot.
Q. For the density curve displayed below, which of the following is true?
A. The mean is larger than the median.
B. The proportion of outcomes between 0.2 and 0.5 is equal to 0.3.
C. The proportion of outcomes exceeding 1.5 is equal to 0.25.
