Chapter 21, Problem 11PDQ
Corn plants from a test plot are measured, and the distribution of heights at 10-cm intervals is recorded in the following table:
| Height (cm) | Plants (no.) |
| 100 | 20 |
| 110 | 60 |
| 120 | 90 |
| 130 | 130 |
| 140 | 180 |
| 150 | 120 |
| 160 | 70 |
| 170 | 50 |
| 180 | 40 |
Calculate (a) the mean height, (b) the variance, (c) the standard deviation, and (d) the standard error of the mean. Plot a rough graph of plant height against frequency. Do the values represent a normal distribution? Based on your calculations, how would you assess the variation within this population?
