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 peas are randomly selected in groups of 18. 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 18.
the value of the mean is μ = 13.5 peas. (type an integer or a decimal. do not round.)
the value of the standard deviation is σ = 1.8 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.)

Explanation:

Step1: Recall range - rule - of - thumb formula

Significantly low values are $\mu - 2\sigma$.

Step2: Substitute given values

We know $\mu = 13.5$ and $\sigma=1.8$. So, $13.5−2\times1.8$.

Step3: Calculate the result

$13.5−3.6 = 9.9$.

Answer:

9.9
