Chapter 8: Q 63. (page 541)

Weeds among the corn Velvetleaf is a particularly annoying weed in cornfields. It produces lots of seeds, and the seeds wait in the soil for years until conditions are right for sprouting. How many seeds do velvetleaf plants produce? The histogram shows the counts from a random sample of 28plants that came up in a cornfield

when no herbicide was used. Determine if the Normal/Large Sample condition is met in this context.

Short Answer

Expert verified

The condition of normality does not meet.

Step by step solution

01

Given Information

We are given the graph as below:

02

Explanation

  • The distribution shape is left skewed with two outliers.
  • It implies distribution is right skewed with outliers.
  • Hence, it cannot be normal distribution.
  • Therefore, to usetdistribution, normal distribution is not met.
