Question

Assume that hybridization experiments are conducted with peas having the property that for​ offspring, there is a

0.250.25

probability that a pea has green pods. Assume that the offspring peas are randomly selected in groups of

3030.

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

3030.

The value of the mean is

muμequals=

peas.

​(Type an integer or a decimal. Do not​ round.)

The value of the standard deviation is

sigmaσequals=

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

peas or fewer are significantly low.

​(Round to one decimal place as​ needed.)

Values of

0.0086310.008631

peas or greater are significantly high.

​(Round to one decimal place as​ needed.)

c. Is a result of

22

peas with green pods a result that is significantly​ low? Why or why​ not?The result

is

is not

is

significantly​ low, because

22

peas with green pods is

less than

equal to

greater than

less than

nothing

peas.
