Question

o Assume that to experiments we conducted with peas having the property that for offspring. There is a 0.75 probability that a peahoon pods. Assume the otpring peas are randomly selected in groups of 22. Complete parts a. Find the meat and the standard deviation for the numbers of pens with green pods in the groups of 22. The value of the meanism Type age or a decimal Do not found) The of the standard deviation pas Round to be deal places needed) b. Use the norge rule of thumb to find the value ting results that are granty low or any Valves as were signo Round to one domaceased) Values opens with pods are the low? Whyer why not? peas The equo great han

Answer 1

Sell (a) Given: h=22 p = 0.75 The value of mean en M = np - 22x0.75 16.5 The value of Standard deviation (C)= moltes = /22x0.75 x (1-0.75) = 4.125 22.031 12.0 (Round to one decimal place) (6) According to tange rule of thumb, most values should life within 2 standard deviations of the mean. Lower limit 16.5 -2x 2.031=12:438 Values of (12.4 peas of fewer are significantly low. Upper limit M+20= 16.5 + 2x2.031 = 20.562 values of 20.6 peas of greater are signifactly high. As the value 7 lies below the lower limit of 12.4 The result is significantly low, because 7 peal with green pods is I less than 12.4 peas. u-20
