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

- Just simply answer the question.arrow_forwardA 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_forwardDr. Loras Tyrell was curious to see if his students actually saved money by purchasing books from sources other than the college bookstore. He administered a survey to all his students asking how they obtained their book (Bookstore, Rented, ebook, or on the web – WebBooks) and how much they paid for the book. He obtained the information below. If the values for web-books are normally distributed, we know that of the students who purchased their book on the web (WebBooks), about 68.3% of those students paid approximately $----- to ----?arrow_forward
- Costume designers are fashion designers that design costumes for the performing arts and for motion picture and television productions. They research the styles worn during the period in which the performance takes place, or work with directors to select and create appropriate attire. They must stay within the costume budget for the production. An upcoming play requires 6 bunny costumes. Each costume requires 3 square yards of faux fur. Faux fur costs $9.50 per square yard and the costume budget for the bunny costumes is $200. What is the total cost of material for the bunny costumes? $arrow_forwardAnswer it correctly and explain well.

To accommodate the increase in business during the summer vacation season, Fuzzy Conch, the owner, hires a large number of servers as seasonal help. When he interviews a prospective server, he would like to provide data on the amount a server can earn in tips. He believes that the amount of the bill and the number of diners are both related to the amount of the tip. He gathered the following sample information.

These slots are called facings. The manager of the coffee shop suspects that the distribution of juice sales is different than the distribution of facings for each type of juice, so the manager records the sales of each juice over a two-week period. The proportion of facings and the sales for each type of juice are shown in the tables. Does the coffee shop owner have sufficient evidence to conclude that the distribution of sales is proportional to the number of facings at a 5 percent level of significance? Conduct the appropriate statistical test to support your conclusion.arrow_forwardComplete the table by filling in the values of LB (lower boundaries) andarrow_forward
- One of the world's leading cycling magazine reviews hundreds of bicycles throughout the year. Their "Road-Race" category contains reviews of bikes used by riders primarily interested in racing. One of the most important factors in selecting a bike for racing is the weight of the bike. The following data show the weight (pounds) and price ($) for 10 racing bikes reviewed by the magazine.

Let us concentrate on the second part for now. A certain gardening magazine conducted a survey to determine how many people have planted a tree in their life. The results stated that 13%of the respondents have planted at least one tree. QUESTION: For the margin of error to be 1%, how many people should be surveyed? Round up to the nearest whole number, if necessary.arrow_forward
