A college student is conducting a survey to see if students prefer cats or dogs. They survey 100 randomly selected college students and asked them, "Are you a cat person or a dog person?" The distribution of possible responses of the 100 college students is an example of a binomial distribution. O true O false

A player pays $5 to play a card game where he chooses a random card from a well shuffled deck of cards. He wins $15 if it's an Ace, $10 if it's a Face card and $5 if it's a Ten. a) Construct a distribution for the outcomes of this game where X is the amount of winning. Hint: X = $10, $5, $0 and $-5.

Organ Donors USA Today provided information about a survey of 5100 adult Internet users. Of the respondents, 2346 said they are willing to donate organs after death. In this survey conducted for Donate Life America, 100 adults were surveyed in each state and the District of Columbia, and results were weighted to account for the different state population sizes. a. What percentage of respondents said that they are willing to donate organs after death? b. Based on the poll results, what is the probability of randomly selecting an adult who is willing to donate organs after death? c. What term is used to describe the sampling method of randomly selecting 100 adults from each state and the District of Columbia?

A group of 11 students was selected at random and asked for their high school GPA and their freshmen GPA in college the subsequent year. The results were: Student High School GPA Freshmen GPA 1 2.0 1.6 2 2.2 2.0 3 2.6 1.8 4 2.7 2.8 5 2.8 2.1 6 3.1 2.0 7 2.9 2.6 8 3.2 2.2 9 3.3 2.6 10 3.6 3.0 We would like to know whether there is a linear relationship between the high school GPA and the college freshmen GPA, and we would like to be able to predict the freshmen GPA, if we know that the high school GPA of another student is, say, 3.4. Provide the two requested scatter plots for this data (put college freshman GPA on the Y (vertical) axis!). a) What would be your approximate 95% prediction interval for question (g)? b) Show your scatterplot with the predicted trend line below
A health psychologist claims that the more final exams a student has during finals weeks, the more stressed they are. They want to test this experimentally by having 6 students receiving additional finals in their fall semester and then assessing sleep during finals (uį = mu1). Then the same 6 students receive no additional finals in their spring semester and are assessed on their sleep during finals (u2 = mu2) and they want to assess if the difference in sleep with additional finals relative to no additional finals with mu1 - mu2. µ1 = mu1 = Additional finals and µ2 = mu2 = No additional finals They get the following data: Additional Final Exams No Additional Final Exams 88 66 76 43 54 59 63 72 53 58 84 48 What would be the mean difference (i.e., the numerator of your t statistic)? Please compute and report to 4 decimal places.
