2. The STAT 3450 HW1 Question 2 Data spreadsheet on Carmen contains the BMI and Systolic BP for all 500 systolic BP, and the third is BMI). Use Minitab, IMP, or another statistical program to generate 5 statistics below. For each table, write a sentence or two summarizing your results. individuals in a population (the first column is observation number, the second is rent random samples of size s0. For each sample, compute and record the summary SysBp Min Median Q3 Max Mean SD 01 21.as121.e 7.3 1a0 121 Max Mean SD 03 21.888 BMI Min Q1 Median 30 a4-34 15 T.910 17.918

Explanation / Answer

(a) From the SysBp table, we can say that the samples don't contain any outliers, since the values of means and medians are more or less close to each other. Variation within these 5 samples is also more or less the same. The samples seem to be a bit positively skewed, since in most of the cases, the values of the means are slightly greater than that of the medians.

(b) In the BMI table, we can also say that the samples don't contain outliers, since the values of means and medians are more or less the same. Variation within each of the samples is also more or less the same. The samples, though, seem to be a bit negatively skewed, since in most of the cases, the values of the means are slightly lesser than that of the medians.
