The sample size was weingThe students in an Introductory Statistics class are asked to complete a survey about study habits. (a) does the study appear to use random sampling? yes or no (b) does the study appear to use random assignment? yes or noA social scientist gathers a carefully chosen group of 20 people whom she is selected to represent a broad cross section of the multiple of the population in New York City. She interviews them in depth for a study that she is doing regarding race relations in the city. Is there a probability sample? Explain your answer.
- In a statistics class, students are given a homework assignment which can be described as the followings: (a) develop an experiment; (b) design a question; and (c) determine a probability distribution based upon the experiment you developed. One student develops an experiment: he puts 20 balls in a black box (i.e., it is not possible to see inside). These 20 balls include 15 white balls and 5 red balls. He closes his eyes and randomly selects 3 balls without replacement from this box. He designs a question: what is the probability that he exactly picks 2 red balls? He finally claims that this experiment is the binomial experiment, which means that the random variable is the binomial probability distribution. His reason is: you either pick white ball or red ball, so there are only two outcomes. It is impossible that you can have the third outcome. Therefore, it is a binomial experiment. Do you agree with the student’s claim? Does it make any sense? Why or why not? Discuss and explain…A bowl of candy contains 21 green, 8 white, and 16 orange candies. TWO candies are randomly selected from the bowl. d) Find the number in the sample space of this experiment. n(S)= ? Write your answer as a whole number. e) Find the probability of event E: selecting 1 white candy and 1 orange candy. p(E)= ? Write your answer as a percent rounded to one decimal place.Sampling with Replacement The Orangetown Medical Research Center randomly selects 100 births in the United States each day, and the proportion of boys is recorded for each sample. a. Do you think the births are randomly selected with replacement or without replacement? b. Give two reasons why statistical methods tend to be based on the assumption that sampling is conducted with replacement, instead of without replacement.
