Chapter 4 Hw Biostatistics Answers

CHAPTER 4 HW Due: Wednesday 2/15/11 final result every(prenominal) questions by hand (i.e., show your work): 1.List three methods of charge probabilities. (1 point) equ every last(predicate)(prenominal)y likely outcomes, relative frequency, intuition 2. A botanist has significant a new hybrid cotton plant that can withstand insects better than other cotton plants. However, there is some(prenominal) concern about the germination of seeds from the new plant. To look the arithmetic mean that a seed from the new plant leave crapper germinate, a random model of 3000 seeds was planted in warm, damp soil. Of these seeds, 2430 germinated.

Explain. severalisener off or not germinate. Yes they should minimal brain dysfunction to 1 because those are the wholly outcomes. b ) ar the outcomes in the sample space or part (a) every bit likely? No. The seeds are much likely to germinate. c) office relative frequencies to estimate the probability that a seed will germinate. What is your estimate? P(germinate) = d) Use relative frequencies to estimate that the seed will not germinate. P(not germinate) = 3.

Roll a (fair, six-sided) go through: (4 possible points) a) If you trilled wave a maven disclose and count the number of dots on top, what is the sample space of all possible outcomes?

Should they add up to 1? Explain. 1/6 for each outcome. Yes they add up to 1. Yes they should because each of the 6 sides is equally likely and represents all of the possible outcomes. The probability of rolling either 1,2,3,4,5 or 6 = 1. c) What is the probability of getting a number less than 5 on a single throw? Outcomes include : 1,2,3,4 that is quartet favorable outcomes 4/6 = 2/3 d) What...If you unavoidableness to get a full essay, ordinance it on our website: OrderCustomPaper.com
