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 muequals=7.57.5 peas. (Type an integer or a decimal. Do not round.) The value of the standard deviation is sigmaequals=2.42.4 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 3030 peas or fewer are significantly low. (Round to one decimal place as needed.) Values of nothing 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 not is significantly low, because 22 peas with green pods is greater than equal to less than nothing peas. (Round to one decimal place as needed.)

Explanation / Answer

b) Significantly low value = 7.5 - 2*2.4 = 2.7

Significantly high value = 12.3

c) is; Less than; 2.7
