Chapter 4 Hw Biostatistics Answers

CHAPTER 4 HW Due: Wednesday 2/15/11 tell every(prenominal) questions by hand (i.e., show your work): 1.List three methods of charge probabilities. (1 point) equ tout ensembley likely outcomes, relative frequency, intuition 2. A botanist has satisfying a new hybrid cotton plant that fundament withstand insects better than other cotton plants. However, there is some(prenominal) concern about the germination of seeds from the new plant. To infer the facial expression that a seed from the new plant leave hindquarters germinate, a random model of 3000 seeds was planted in warm, dampish soil. Of these seeds, 2430 germinated. (4 doable points) a) Either the seed lead germinate or it bequeath not. What is the sample pose in this problem? Should the probabilities depute to the sample space get up to 1? Explain. replicate or not germinate. Yes they should minimal brain dysfunction together to 1 because those are the just outcomes. b) ar the outcom es in the sample space or parti onlyy (a) every bit likely? No. The seeds are more than 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) frighten off: (4 possible points) a) If you trilled wave a maven exit and count the number of dots on top, what is the sample space of all possible outcomes? Are the outcomes as likely? Sample space: 1,2,3,4,5,6; They are equally likely. b) lot probabilities to the outcomes of the s! ample space in part (a). Do the probabilities add up to 1? 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 4 favorable outcomes 4/6 = 2/3 d) What...If you postulate to get a full essay, ordinance it on our website: OrderCustomPaper.com
