The Sander’s family owns a large grape vineyard in Jackson,
Mississippi. The grape vines must be sprayed at the beginning of
the growing season to protect against various insects and diseases.
Two new insecticides have just been marketed: Pernod 5 and Action.
To test their effectiveness, three long rows were selected and
sprayed with Pernod 5 and three other were sprayed with Action.
When the grapes ripened, 400 of the vines treated with Pernod 5
were checked for infestation. Likewise, a sample of 400 vines
sprayed with Action was checked. The results are:
Number of
Vines Checked Number of
Insecticide (sample size) Infested Vines
Pernod 5 400 24
Action 400 40
At the .04 significance level, can we conclude that there is a
difference in the proportion of the vines infested using Pernod 5
as opposed to Action?
please show all steps and work.

In a backyard vineyard in Napa Valley with 10 grape
vines in a row, if the weather works well (just right), rain in the
Spring and dry through summer, the yield for each vine is
distributed roughly binomial with N=800, p=0.5. In a drought the
yield is Binomial with N=800 and P=0.48, while if the year is too
wet, the yield of useful grapes per vine is N=600, P=0.2. Under
climate change the probability of just the right year is...

VVI’s vineyard sources its wine from ten plots of land in
separate locations from two
acres to twenty acres. Each vineyard has its own unique name,
such as Rattlesnake
Canyon, Red Fox, Theresa’s, etc. and is either owned by VVI or
by an independent third
party. Each is managed by a single employee. No employee manages
more than one
vineyard. The location and size,...
