- Repeat Example 5 when microphone A receives the sound 4 seconds before microphone B.An analyst in the real estate business is interested in the relationship between the cost of the monthly rent of an apartment and the size of an apartment, in big cities. She gathers data for apartment buildings in 12 cities in 12 different states. In each city, she gets the numbers for at least 5 different buildings and at least 40 apartments in each building. She reaches the following conclusion: the rental cost of a 2-bedroom apartment is 50% more than the rental cost of a 1-bedroom apartment, and the rental cost of a 3-bedroom apartment is 50% more than the rental cost of a 2-bedroom apartment. Based on the paragraph, what is the minimum number of apartments she collected data on? Do you think her sample was large enough to be statistically valid? Based on the paragraph, are there any apartments or apartment buildings that she would have excluded from her study? Do you see any bias in how she selected apartments for her study? Based on the paragraph, is there a positive…C. How likely are you to randomly select a consumer who cannot live without several of the products under consideration?

- Jo, a store owner, has an option of selling hot drinks or halu-halo during a championship game. The profits will depend on weather conditions. On a clear day, the profits will be P 1,500 and P9,000 on a rainy day if she sells hot drinks. If she sells halu-halo, her profits will be P 10,000 on a clear day and P5,000 an a rainy day. It was learned that during the time of the year 65% of the days are clear and 35%) are rainy. What type of refreshments should the owner sell? Make a decision tree and state your decision.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 belowIn what sense is the mean teh center of distributon? a.M is the center because half the sample scores are always above it and half are below b.M is center because it is always the most probable score in the sample c.M for the sample always equals micro for the population d.M is like a balance point because E (m-x)=0 for every sample.
- An experiment, in chemistry, was done where first a person tried to solve a problem with two possible results A or B. A second experiment was then done, with the materials from the first, which results C, after the student had gotten result A. Which of the following best describes this: P(A|B)P(C) or P(A)P(C) or P(A)P(C|A&B) or P(A)P(C|A)2) A) |vk•vl|=0 B) |vk•vl|=||vk|| ||vl|| C) |vk•vl| < ||vk|| ||vl|| D) the information given does not give us any information about |vk•vl|f there is no seasonal effect on people getting sick, we would expect equal numbers of people getting sick in each season (winter, spring, summer and fall). A student takes a census of students who took Marketing Research in 2019 and finds that of the 280 students who took Marketing Research in 2019, 75 were sick in winter, 65 were sick in spring, 68 were sick in summer and 72 were sick in fall. She wonders if the excess in the winter is an indication that sickness rates are not uniform throughout the year. What is an appropriate H1? a. The number of people getting sick is not equally distributed across the four seasons. b. The observed values equal the observed values. c. The number of people getting sick is equally distributed across the four seasons. d. The expected values equal the expected values.
