A teacher randomly chooses a two-person team from a group of four students. The first person chosen will be the presenter and the second person will be the researcher. Two of the students, Amir and Aaron, are boys. The other two students, Caitlin and Deniz, are girls. All the possible outcomes of the team selection are listed below. If we take outcomes 2 3 5 6 7 8 10 2,3,5,6,7,8,10,2, comma, 3, comma, 5, comma, 6, comma, 7, comma, 8, comma, 10, comma and 11 1111 as a subset of the sample space, which of the statements below describe this subset? Choose all answers that apply: Choose all answers that apply: (Choice A) A The subset consists of all the teams not made up of all boys and not made up of all girls. (Choice B) B The subset consists of all the teams made up of one boy and one girl. (Choice C) C The subset consists of all the teams having a girl as the presenter and a boy as the researcher. (Choice D) D The subset consists of all the teams made up of either all boys or all girls.

The difference of three and the reciprocal of a number is equal to the quotient of 20 and the number. find the number.

Listed below are time intervals (min) between eruptions of a geyser. assume that the "recent" times are within the past few years, the "past" times are from around 20 years ago, and that the two samples are independent simple random samples selected from normally distributed populations. do not assume that the population standard deviations are equal. does it appear that the mean time interval has changed? is the conclusion affected by whether the significance level is 0.10 or 0.01? recent 78 90 90 79 57 101 62 87 71 87 81 84 57 80 74 103 62 past 88 89 93 94 65 85 85 92 87 91 89 91 follow the steps of hypothesis testing, including identifying the alternative and null hypothesis, calculating the test statistic, finding the p-value, and making a conclusions about the null hypothesis and a final conclusion that addresses the original claim. use a significance level of 0.10. is the conclusion affected by whether the significance level is 0.10 or 0.01? answer choices below: a) yes, the conclusion is affected by the significance level because h0 is rejected when the significance level is 0.01 but is not rejected when the significance level is 0.10. b) no, the conclusion is not affected by the significance level because h0 is not rejected regardless of whether a significance level of 0.10 or 0.01 is used. c) yes, the conclusion is affected by the significance level because h0 is rejected when the significance level is 0.10 but is not rejected when the significance level is 0.01. d) no, the conclusion is not affected by the significance level because h0 is rejected regardless of whether a significance level of 0.10 or 0.01 is used.
