Undergraduate students at Miami University in Oxford, Ohio, were surveyed in order to evaluate the effect of price on the purchase of a pizza Hut. The students were asked to suppose that they were going to have a large two-topping delivered to their residence. Then they were asked to select from either Pizza Hut or another pizzeria of their choice. The price they would have to pay to get a Pizza Hut pizza differed from survey to survey. For example, some surveys used the price
a. Using half the data as the training sample and the other half of the data as the validation sample, develop a classification tree model to predict the probability the student will select Pizza Hut based on the price of a Pizza Hut pizza and the gender of the student.
b. What conclusions can you reach about the probability the student will select Pizza Hut?

EBK BASIC BUSINESS STATISTICS
- A school superintendent wanted to know whether there were differences between the high schools in her district with regards to the proportion of students who do not live with their biological parents. She surveyed 200 students from each of the two high schools – East and West. The proportion of students from the survey at East who do not live with their biological parents is 3.4%. The proportion of students from the survey at East who do not live with their biological parents is 4.2%. Using a 95% confidence interval (2SD or Theory based), can the superintendent conclude that there is a difference between East and West with respect to the proportion of students who do not live with their biological parents. Group of answer choices Yes she can conclude there is a difference because the confidence intervals overlap. No she cannot conclude there is a difference because the confidence intervals overlap. Yes she can conclude there is a difference because the confidence intervals don’t…arrow_forwardThe UNOH good works society is planning an annual fundraising "Eat-a-Thon". The society will charge students 75¢ per serving of pasta. The only expenses they will incur are the cost of the pasta, estimated at 25¢ per serving, and the $325 cost of renting the facility for the evening. Perform a Break-Even analysis. How many servings of pasta would they need to sell to make money for the fundraiser? Select one: O a. They would need to sell 651 servings of pasta. b. They would need to sell 851 servings of pasta. O c. They would need to sell 451 servings of pasta. o d. They would need to sell 551 servings of pasta. O e.

- A survey of a random sample in an amusement park showed an average expenditure of $10.30 for the evening. The average expenditure for the 20 girls in the sample was $9.70 and for the boys it was $11.10. How many boys are there in the random sample?arrow_forwardA study investigated whether price affects people's judgment. Twenty people each tasted six cabernet sauvignon wines and rated how they liked them on a scale of 1 to 6. Prior to tasting each wine, participants were told the price of the wine. Of the six wines tasted, two were actually the same wine, but for one tasting the participant was told that the wine cost $10 per bottle and for the other tasting the participant was told that the wine cost $90 per bottle. The participants were randomly assigned either to taste the $90 wine first and the $10 wine second, or the $10 wine first and the $90 wine second. Differences were calculated by subtracting the rating for the tasting in which the participant thought the wine cost $10 from the rating for the tasting in which the participant thought the wine cost $90.

In 2017, the median income of American households was $68,145. The mean household income was $93,453. The median income of families was $75,938, and the mean family income was $100,400. The Census Bureau says, "Households consist of all people who occupy a housing unit. The term 'family' refers to a group of two or more people related by birth, marriage, or adoption who reside together." Explain carefully why mean incomes are higher than median incomes and why family incomes are higher than household incomes.arrow_forward

She also wants to test whether people's attitude towards vegan food (measured on a 7-point Likert scale ranging from 1 = do not like at all, 7 = like a lot) influences this relationship. Thus, she wants to test whether coffee preferences depends on income and attitudes towards vegan food.
