#44: The Higher Education Research Institute at UCLA collected data from 203,967 incoming first-time, full-time freshmen from 270 four-year colleges and universities in the U.S. 72.5% of those students replied that, yes, they believe same-sex couples should have the right to legal marital status. Suppose that you randomly pick eight first-time, full- time, freshmen from the survey. You are interested in the number that believe that same- sex couples should have the right to legal marital status. (Bold #'s are randomized.) Round probabilities to five decimal places. Do not use scientific notation. What is the probability that at least two of the freshmen reply "yes"? BinomialDist( Check Next page II
2. In a science fair project, Emily conducted an experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or left hand, and then she asked the therapists to identify the selected hand by placing their hand just under Emily's hand without seeing it and without touching it. Among 300 trials, the touch therapists were correct 135 times. Complete parts (a) through (d) a. Given that Emily used a coin toss to select either her right hand or her left hand, what proportion of correct responses would be expected if the touch therapists made random guesses? b. Using Emily's sample results, what is the best point estimate of the therapist's success rate? c. Using Emily's sample results, construct a 99% confidence interval estimate of the proportion of correct responses made by touch therapists. d. What do this result suggest about the ability of touch therapists to select the correct hand by seeing…
In a driver-side "star" scoring system for crash-testing new cars, each crash-tested car is given a rating ranging from one star to five stars; the more stars in the rating. the better is the level of crash protection in a head-on colision. A summary of the driver-side star ratings for 98 cars is reproduced in the accompanying table. Assume that 1 of the 98 cars is selected at random, and let x equal the number of stars in the car's driver-side star rating. Complete parts a through d.

. In a study to investigate the effect of regular physical exercise on the reduction of high blood pressure in males aged 60-65, the researchers selected at random a sample of n₁ =12 males suffering from high blood pressure in the given a 12ge group and for a two-year period placed the subjects on a daily physical exercise program. A second sample of n₂ =12 males suffering from high blood pressure in the given age group was selected and again for the two-year period this group of subjects were placed on a physical exercise program for which they were required to perform only once a week. Finally a third sample of n3 =12 males suffering from high blood pressure in the given age group was selected. No exercise program was required for individuals in sample three. At the end of the two-year period the reduction in blood pressure was measured for each of the subjects in the study and is presented in the table on the next page. Table V.1: Reduction in Blood pressure for three groups of…
A manufacturing company that produces laminate for countertops is interested in studying the relationship between the number of hours of training that an employee receives and the number of defects per countertop produced. Ten employees are randomly selected. The number of hours of training each employee has received is recorded and the number of defects on the most recent countertop produced is determined. The results are as follows. Hours of Training Defects per Countertop 1 5 4 1 7 0 3 3 2 5 2 4 5 1 5 2 1 8 6 2 Copy Data The estimated regression line and the standard error are given. Defects per Countertop=6.717822−1.004950(Hours of Training)se=1.229787se=1.229787 Suppose a new employee has had 5 hours of training. What would be the 90% prediction interval for the number of defects per countertop? Round your answer to two decimal places.

In a study of how the environment affects spending, researchers varied the presence of music and scents in a shopping mall. Interviews with shoppers who made unplanned purchases revealed the average purchase amounts shown to the right. Each group has 100 shoppers. Complete parts (a) through (c) below. (a) If each group includes 100 shoppers, which group spent the most money in total? Condition None Scent Music Scent and music A. The group that was exposed to only music spent the most money in total. B. The group that was exposed to only scent spent the most money in total. C. The group that was exposed to both scent and music spent the most money in total. D. The group that was exposed to neither scent nor music spent the most money in total. (b) If medians summarized each group's spending rather than means, would you be able to identify the group with the largest spending? A. No, the total amount cannot be recovered from the median value. B. Yes, the total amount can be recovered from…
Suppose a researcher is interested in examining the relationship between a person's gender and whether he or she likes the taste of Vegemite (a dark- brown food paste, made from yeast, that is popular in Australia). She collects a sample of n = 10 people and asks them whether they like the taste of Vegemite. The following table summarizes the results. Male Female Does Not Like the Taste of Vegemite 4 1 Likes the Taste of Vegemite 2 3 The researcher wants to calculate the correlation between a person's gender and whether he or she likes the taste of Vegemite. To do so, the researcher first creates a table of the data by converting each variable to a numerical value. She assigns 0 to "male" and 1 to "female." She then assigns 0 to "does not like the taste of Vegemite" and 1 to "likes the taste of Vegemite."
Itranscript One male and one female dam rat pup were randomly selected from 8 litters to perform the swim maze. Each pup was placed in the water at one end of the maze and allowed to swim until it escaped at the opposite end. If the pup failed to escape after a certain period of time, it was placed at the beginning of the maze and given another chance. The experiment was repeated until each pup accomplished three successful escapes. The table to the right reports the number of swims required by each pup. Is there sufficient evidence of a difference between the mean number of swims required by male and female pups? Use a=0.01. Comment on the assumptions required for the test to be valid.
