1. What is the median height of the students? 2. From visual inspection alone, the median of the distribution is: A. Substantially greater than the mean C. Exactly equal to the mean B. Substantially less than the mean D. Too hard to tell D. Approximately equal to the mean 3. From visual inspection alone, the distribution of the variable height is clearly: A. Skewed negatively B. Skewed positively C. Perfectly symmetric

Question

I need help with 1,2,3

Consider the following stem-and-leaf display with regard to the heights (in inches) of a simple random sample of 35 male students at Zarthan college: Stem Leaf 8 01 7 00111233466789 6 59 1. What is the median height of the students? 2. From visual inspection alone, the median of the distribution is: 011233444556777899 A. Substantially greater than the mean C. Exactly equal to the mean A. Skewed negatively 3. From visual inspection alone, the distribution of the variable height is clearly: B. Skewed positively D. Too hard to tell A. Greater than 12 4. From visual inspection alone, the standard deviation of the height distribution is: Stem Leaf 8 7 7 6 B. Substantially less than the mean 6 5 D. Approximately equal to the mean B. Less than 12 5. Construct a stem-and-leaf plot that divides the data into intervals of length 5 inches. C. Perfectly symmetric C. Cannot tell without calculating
