Significance with Range Rule of Thumb. In Exercises 31 and 32, 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 (as in one of Mendel’s famous experiments). Hybrids Assume that offspring peas are randomly selected in groups of 16.

a. Find the mean and standard deviation for the numbers of peas with green pods in the groups of 16.

b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high.

c. Is a result of 7 peas with green pods a result that is significantly low? Why or why not?

Step 1

a.

**Mean:**

The mean number of peas with green pods in the groups of 16 is,

Step 2

**Standard deviation:**

The standard deviation for the number of peas with green pods in the groups of 16 is,

Step 3

b.

**Range rule of thumb:**

The range rule of thumb is µ±2σ and the values which fall outside this range is said to be signi...
