(a) There are

European cities that Rita would eventually like to visit. On her next vacation, though, she only has time to visit

of the cities: one on Monday, one on Tuesday, one on Wednesday, and one on Thursday. She is now trying to make a schedule of which city she'll visit on which day. How many different schedules are possible? (Assume that she will not visit a city more than once.)

(b) An experiment involves

participants. From these, a group of

participants is to be tested under a special condition. How many groups of

participants are possible?

8. A local 7-Eleven sells a “Memory Pill" that is supposed to help people...um...remember. You find some Oxnard College students and randomly divide them into two groups of 15 students each. One group takes the actual "Memory Pill" and the other group takes the placebo. You then show them a list of 20 items and want them to remember as many as possible. The experimental group (those taking the pill) remembered an average of 12.3 items from the list, with a sample standard deviation of 5.4. The control group (with the placebo) remembered an average of 10.9 items, with a sample standard deviation of 4.2. Is this enough evidence to show that the "Memory Pill" improves...well...memory?

A psychologist wants to know whether viewing more violent TV shows affects aggressive behavior. 12 children were chosen at random for an experiment and randomly allocated to one of two conditions. In condition 1, six kids were given an aggressive behavior test. The more aggressive the conduct, the higher the score. In condition 2, six children were given the identical test after watching two hours of tv shows. The following results were obtained. Condition 1 5 14 6 8 7 6 Condition 2 12 14 14 8 15 9 Assume the obtained value of the appropriate statistic is t obt = -2.431, using α = 0.05, 2 tail, and t crit = +2.228 and -2.228, what do you conclude? a. retain null hypothesis, suggesting that violent TV show does not affect aggression. b. reject null hypothesis, suggesting that violent TV show affects aggression.
Part A: There is a population of five people. They were each asked how many movies they saw in the last year. Amy saw one (1), Bob saw seven (7), Clara saw thirteen (13), Dora saw nineteen (19), and Earl saw twenty-five (25). Looking at every single possible sample of size three (with replacement). First column will be a list of every single sample (e.g., Amy, Amy, and Amy – or AAA – Amy, Amy, and Bob – or AAB – et cetera). The second column will list the mean of each sample.The third column will list the variance of each sample (using N in the denominator); and the fourth column will list the variance of each sample (using N-1 as the denominator). Calculate the means of the last three columns. To calculate the averages of the columns, put the data in a frequency table and then calculate the mean using the table. Calculate the variance of the population. Look at the values of the numbers. Which one of these means is special? Why? This will have six distinct parts: 1) the…
A report describes a survey of 251 adult Americans. Participants in the survey were asked how often they disinfect their phone and were asked to respond with one of the following categories: more than once a week, once a week, every other, week, every three weeks, or less often than every three weeks. For this group, 9% responded more than once a week, 52% responded once a week, 26% responded every other week, 6% responded every three weeks, and 7% responded less often than every three weeks. Fill in the table below with the relative frequency distributions. How Often? Relative Frequency More than once a week Once a week Every other week Every three weeks Less often than every three weeks

I. In the following study educational researchers were interested in whether a New Method for teaching mathematics was more effective than the Standard Method. A sample of 20 students were taught by the Standard Method, while another sample of 15 students were taught by the New Method. Each student was given a mathematics proficiency test at the end of the teaching period. The scores on this test are tabulated below: Standard 54.2 61.9 69.2 76.1 55.8 67.3 73.9 67.3 73.9 71.4 Method New Method 76.4 69.6 66.0 81.1 66.6 77.2 89.9 85.4 66.3 67.9 77.5 70.3 63.2 33.4 55.6 42.0 13.8 10.7 36.9 71.6 37.9 23.7 14.5 26.6 55.2 Some Summary Statistics are given below: Er Ex?

An anger-management course claims that, after completing its seminar, participants will lose their tempers less often. Always a skeptic, you decide to test this claim. A random sample of 12 seminar participants is chosen, and these participants are asked to record the number of times that they lost their tempers in the two weeks prior to the course. After the course is over, the same participants are asked to record the number of times that they lost their tempers in the next two weeks. The following table lists the results of the survey. Using these data, test the claim at the 0.01 level of significance assuming that the population distribution of the paired differences is approximately normal. Let participants before completing the anger-management course be Population 1 and let participants after completing the anger-management course be Population 2.

Example 1: The owner of a local restaurant chain in town was trying to determine the best location to open her next restaurant and she had narrowed it down to two locations. She wanted to make her decision based on how interested residents in each area were in her restaurant. So she hired an independent company to survey residents from each neighborhood to gauge their interest. In the first neighborhood, 120 residents were surveyed and 84 of them expressed interest in the new restaurant. In the second neighborhood, 200 residents were surveyed and 110 of them expressed interest in the new restaurant. Carry out an appropriate hypothesis test at the a = 0.02 level to determine if there is sufficient evidence to suggest that one neighborhood is more interested in the new restaurant than the other.

You are interested in finding out if kangaroo rats that have been offered food ad lib(unlimited food) for the previous 24 hours store a different amount of food in their pouches than kangaroo rats that have been starved for 24 hours. You take 8 kangaroo rats and starve them for 24 hours, then offer them food and count how many seeds are stored in their pouches in the next hour. You let your rats rest for one week, and repeat the experiment with the same rats, but offer them unlimited food for the 24 hours prior to the experiment. Run the appropriate statistical test.
