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 28. The value of the mean is peas. Type an integer or a decimal. Do not round.) The value of the standard deviation is? ?peas. (Round to one decimal place as needed.) b. Use the range rule of thumb to find the values separating resuits that are significantly low or signfcantly high Values of peas or fewer are significantly low Round to one decimal place as needed.) Values of l peas or greater are significantly high Round to one decimal place as needed) c. is a result of 1 peas with green pods a result that is significantly low? Why or why not? Enter your answer in each of the answer boxesExplanation / Answer
value of the mean =np=28*0.25 =7
std deviation =sqrt(np(1-p))=2.3
b)
value of 7-2*2.3=2.4 peas or fewer are sig. low
value of 7+2*2.3=11.6 peas or greater are sig. high
