#1 A botanist grows a large number of individually potted eggplants, all treated identically. After 30 days, the total leaf area of each plant was measured. The population distribution of the total leaf area was found to be normal with a meanof 800 cm2 and a standard deviationof 90 cm2.
1.1 What percentage of the plants will have a leaf area between 775 cm2 and 825 cm2 ?
1.2 Suppose each group of 4 plants is considered to be a random samplefrom the population. What percentage of the groups will have a group mean leaf area between 775 cm2 and 825 cm 2 ?
This solution considers a botanist who is growing a large number of individually potted eggplants.
