<span>We simplify the equation to the form, which is simple to understand
<span>q+2/5=2q-11/7

Simplifying:
<span>q + 0.4=2q-11/7

Simplifying:
<span>q + 0.4=2q-1.57142857143

We move all terms containing q to the left and all other terms to the right.
<span>+1q-2q=-1.57142857143-0.4

We simplify left and right side of the equation.
<span>-1q=-1.97142857143

We divide both sides of the equation by -1 to get q.
<span>q=1.97142857143</span></span></span></span></span></span></span>

Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.75 probabilit
Verdich [7]

Answer:

a) Standard Deviation = 2.74

b) Significantly Low = values below 24.52 (or equal)

Significantly High = values above 35.48 (or equal)

Step-by-step explanation:

This is binomial probability distribution problem.

Where n = 40 [groups of 40, total trials]

p = 0.75 [probability of success]

a)

The formula for standard deviation is:

Standard \ Deviation = \sqrt{np(1-p)}

We know  n = 40 and p = 0.75, so the standard deviation is:

Standard \ Deviation = \sqrt{np(1-p)} \\Standard \ Deviation = \sqrt{(40)(0.75)(1-0.75)}\\ Standard \ Deviation = 2.74

b)

the range rule of thumb tells us that usual range of values is within 2 standard deviation of the mean. First let's calculate mean.

We know,

Mean = n * p = 40 * 0.75 = 30

So

Mean - 2* Standard Deviation = 30 - 2(2.74) = 24.52

and

Mean + 2* Standard Deviation = 30 + 2(2.74) = 35.48

Significantly Low = values below 24.52 (or equal)

Significantly High = values above 35.48 (or equal)
