Question
Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.75 probability that a pea has green pods. Assume
that the offspring peas are randomly selected in groups of 30. Complete parts (a) through (c) below.
a. Find the mean and the standard deviation for the numbers of peas with green pods in the groups of 30.
The value of the mean isu=
peas.
(Type an integer or a decimal. Do not round.)

a. Find the mean and the standard deviation for the numbers of peas with green pods in the groups of 12.
The value of the mean isu= 9 peas.
(Type an integer or a decimal. Do not round.)
The value of the standard deviation is o = 1.5 peas.
(Round to one decimal place as needed.)
b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high.
Values of 6.0 peas or fewer are significantly low.
(Round to one decimal place as needed.)
Values of 12.0 peas or greater are significantly high.
(Round to one decimal place as needed.)
c. Is a result of 4 peas with green pods a result that is significantly low? Why or why not?
less than
6.0 peas.
The result
is
significantly low, because 4 peas with green pods is
(Round to one decimal place as needed.)
