A survey was conducted to determine whether hours of sleep per night are independent of age. A sample of individuals was asked to indicate the number of hours of sleep per night with categorical options: fewer than 6 hours, 6 to 6.9 hours, 7 to 7.9 hours, and 8 hours or more. Later in the survey, the individuals were asked to indicate their age with categorical options: age 39 or younger and age 40 or older. Sample data follow.

Hypothesis testing with One Way ANOVA. Use hypothesis testing to answer the research questions, labeling each step and completing any post-tests. Researchers want to know if surroundings make a difference in ability to remember a list of words. They test this by randomly assigning subjects to three conditions: shopping mall setting, driving in a car setting (simulation) and in an outdoor setting. Here are the memory scores for each condition: Mall Condition Driving Condition Outdoor Condition 8 8 15 7 7 10 8 5 12 6 8 9 9 10 14 12 10 10 7 12 8 8 8 10

Music and memory Is it a good idea to listen to musicwhen studying for a big test? In a study conducted by some Statistics students, 62 people were randomly as-signed to listen to rap music, music by Mozart, or no music while attempting to memorize objects pictured ona page. They were then asked to list all the objects theycould remember. Here are summary statistics: a) Does it appear that it is better to study while listeningto Mozart than to rap music? Test an appropriatehypothesis and state your conclusion. b) Create a 90% confidence interval for the mean differ-ence in memory score between students who study to Mozart and those who listen to no music at all.Interpret your interval.

An experiment consists of drawing two numbers out of a hat one after the other containing the numbers 1, 3, 5, 6. The two numbers are then recorded as a 2-digit number. The number drawn is NOT put back in the hat before drawing the second. Do the following: List the sample space.________________________________ Let F = the event of getting a number whose first digit is odd Let S = the event of getting a multiple of 6 Find P( F and S) =____________________________________ Find P(F) =______________________________ Find P(F|S) =_______________________________________ Are F and S independent events? ___________Justify_____________ VIII (15) Let E be the event that at least two people out of 4 have the same birth month (not day).

Perform a statistical analysis / test of hypothesis Suppose a researcher wants to see whether teaching students to read using a computer game gives better results than teaching with a tried-and-true phonics method. She randomly selects 20 students and puts them into 10 pairs according to their reading readiness level, age, IQ, and so on. She randomly selects one student from each pair to learn to read via the computer game, and the other learns to read using the phonics method. At the end of the study, each student takes the same reading test. The data are shown in the following table. Student Pair 1 2 3 4 5 6 7 8 9 10 Reading Score under Computer Method 85 80 95 87 78 82 57 69 73 99 Reading Score under phonics method 80 80 88 90 72 79 50 73 78 95 Test whether there is a significant difference between the computer method and the phonics method. If there is a significant difference, which particular method…
