Chapter 4~5 TestName: __________________ Date: __________________ Chaffey College Prof. Garcia Summer 2020 Directions: Answer each question to the best of your ability. Showing work is required for each problem and any answers without work will not receive credit. Furthermore, to receive full credit, all fractions must be reduced, all decimals must be rounded appropriately, and all answers must be boxed when possible. PROBABILITY: 1) Suppose you roll a six-sided die, what is the probability that you roll an odd number OR a number bigger than 3? 2) A standard 52 card deck contains 4 different suits: Hearts, diamonds, clubs, and spades. There are 13 hearts (red), 13 diamonds (red), 13 clubs (black), 13 spades (black). The 4 suits each contain the following cards: A,2,3,4,5,6,7,8,9,10, Jack, Queen, King. An image of these 52 cards is provided along these files on Canvas. In a 52 card deck, what is the probability of randomly pulling a Queen or a Red card? Also, interpret this probability. 3) Suppose you are going to roll a 20 sided die which contains the number 1 through 20. What is the probability that you do NOT roll a single digit number? Use the following table for problems 4-6: 4) If you randomly select one student, what is the probability that they are a part-time student, given that they visit tutoring one or fewer times? 5) If you randomly select one student, what is the probability that they visit tutoring one or fewer times, given that they are a part-time student? 6) If one student is randomly selected, what is the probability that they are a full time student OR that they go to tutoring four or more times? LINEAR REGRESSIONS A rather cold city wishes to know if there is a relationship between temperature (in degree F), X, and the number of passengers on a specific bus line, Y. They recorded the total number of passengers and temperatures on specific dates and organized it into the following list: X Y 42 173 37 149 46 185 30 123 50 201 43 174 43 175 46 188 46 186 49 198 7) Is it appropriate the create a least squares regression line for this data? If so, write the equation of the least squares regression line for this data, and if not, explain why. 8) Predict the number of passengers that will ride the bus if the temperature is 45 degrees. Then, predict the number of passengers that will ride the bus if the temperature is 25 degrees. 9) Interpret the slope (a) of the LSR line. 10) Interpret the intercept (b) of the LSR line.
