The manufacturer of a low-calorie dairy drink wishes to compare the taste appeal of a newformula (formula B) with that of the standard formula (formula A). Each of four judges is giventhree glasses in random order, two containing formula A and the other containing formula B.Each judge is asked to state which glass he or she most enjoyed. Suppose that the two formulasare equally attractive. Let Y be the number of judges stating a preference for the new formula.2.1.1 How can the mean and standard deviation be calculated2.2.2 Interpret the mean = 1.3333 and the standard deviation = 0.9428 of Y

(adapted from Johnson, 1980) Each semester, there are seven sections of a particular biology course, taught at various times by various instructors. The table below shows the number of students who selected each of the seven sections in Fall 2016. Do the data suggest that students have a preference for certain sections of the course? Perform a test of hypothesis using a = 0.05. In answering, be sure to address each of the five steps in a test of hypothesis. Number of students 1 18 2 12 3 25 Section 4 23 5 8 6 19 7 14
The manager of a local record store is interested in the effectiveness of an advertisingcampaign on sales. They randomly select 10 popular CDs (all in the Billboard top 100),and place an ad in the local school newspaper saying that the store has these (and more)in stock. They measure the sales of these 10 CDs for 1 week prior to the ad, and then for1 week after the ad. The number of CDs sold each week is presented below. Was there anincrease in the number of CDs sold after the ad?

The manager of a theater that is open to residents of two towns, A and B, wants to know if the proportion of households from A that use the library is smaller than the proportion of households from B. In order to test this, the manager asks 45 households in A and 49 households in B whether anyone in their household had used the theater last summer. 23 of the households surveyed in A responded "yes", and 35 of the households in B responded "yes". Find the p-value that would be used to make a conclusion for this hypothesis test.

A dairy farmer thinks that the average weight gain of his cows depends on two factors: the type of grain that they are fed and the type of grass that they are fed. The dairy farmer has four different types of grain from which to choose and three different types of grass from which to choose. He would like to determine if there is a particular combination of grain and grass that would lead to the greatest weight gain on average for his cows. He randomly selects three one-year-old cows and assigns them to each of the possible combinations of grain and grass. After one year he records the weight gain for each cow (in pounds) with the following results. Is there sufficient evidence to conclude that there is a significant difference in the average weight gains among the cows for the different types of grain?

Ida wants to know if people prefer for one brand of chocolate chip cookie dough over another. To test this, she bakes eight dozen cookies from dough made by each of 4 manufacturers and labels the brands A, B, C, and D, to conceal the name of the company from the tasters. She then selects a random sample of 96 students at her school to try each brand of cookie and choose the brand they like best. The cookies are tasted in random order. Here are the results: Cookie Brand Number of choosing brand A 26 18 24 28 Ida performs the appropriate y procedure to test the hypothesis that the brands are preferred equally.

Assume that the U.S Open Golf Tournament was played at Congressional Country club, with prizes ranging from $465,000 for first place to $5000. Par for the course is 70. The tournament consists of four rounds played on different days. Suppose the scores for each round of the 32 players who placed in the money (more than $17,000) were given on a web site.

A creative entrepreneur has created a novelty soap called jackpot. Inside each bar of jackpotsoap is a rolled-up bill of U.S. currency. There are 1000 bars of soap in the initial offeringof the soap. Although the denomination of the bill inside a bar of soap is unknown,the distribution of bills in these first 1000 bars is given in the following table: How many bars of soap does a customer have to buy so that, on average, she has purchasedtwo containing a $50 or $100 bill? (hint: Use the hypergeometric distribution inASP to answer this question.)
1. For her botany class project, Jennifer wonders if there is a connection between the average weight of watermelons a vine produces and the root depth of the vine. Jennifer suspects that vines with deeper roots have a better water supply and produce larger melons. From a large watermelon field, 10 vines are chosen at random. At the end of 8 weeks, the watermelons are removed from each vine and the average weight of the watermelons from each vine is determined. Each plant is carefully dug up and its root depth (or length) is measure. Let x represent the root depth (to the nearest inch) and y be the mean weight of the watermelons on the vine (in pounds). Suppose that x = 17, s, = 6, y = 12, s, = 5.1, and r = = 0.93. a. Find the equation of the least squares regression line (round a and b to the nearest tenth). b. List 2 points that you know will be on the least-squares line you found in part a. c. What percent of variation is accounted for by a linear relationship? d. Using part a.,…
