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?

Question
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?
