6)A survey of adults in the United States found that 60% ate at a restaurant at least once in the past week. You randomly select 28 adults and ask them whether they ate at a restaurant at least once in the past week
(a) Verify that a normal distribution can be used to approximate the binomial distribution.
(b) Find the probability that at most 13 adults ate at a restaurant at least once in the past week.

A survey of U.S. adults found that 62% of women believe that there is a link between playing violent video games and teens exhibiting violent behavior. You randomly select four U.S. women and ask them whether they believe that there is a link between playing violent video games and teens exhibiting violent behavior. 1. Construct and graph the binomial probability distribution. 2. Find the probability that (i) exactly three of them respond yes, (ii) at most three of them respond...
Decide whether you can use the normal distribution to approximate the binomial distribution. If you can use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot explain why and use the binomial distribution to find the indicated probabilities A survey of adults found that 8% say their favorite sport is auto racing. You randomly select 600 adults and ask them to name their favorite sport. Complete parts (a) through (d). Determine whether a normal...
1) In a survey, 2276 adults in the United States, it was found that 33% of those surveyed never travel using commercial airlines. [Spts) (a) Determine whether the study is an experimental or an observational study (b) Identify the sample and the population (c) Is the value 33% a statistic or a parameter?
A binomial experiment is given. Decide whether you can use the normal distribution to approximate the binomial distribution. If you can, find the mean and standard deviation. If you cannot, explain why. A survey of adults found that 5454% have used a multivitamin in the past 12 months. You randomly select 6060 adults and ask them if they have used a multivitamin in the past 12 months. Select the correct answer below and, if necessary, fill in the answer boxes...
A binomial experiment is given. Decide whether you can use the normal distribution to approximate the binomial distribution. If you can, find the mean and standard deviation. If you cannot, explain why. A survey of adults found that 43% have used a multivitamin in the past 12 months. You randomly select 40 adults and ask them if they have used a multivitamin in the past 12 months. Select the correct answer below and, if necessary, fill in the answer boxes...
The United States Department of Agriculture (USDA) found that the proportion of young adults ages 20–39 who regularly skip eating breakfast is 0.238. Suppose that Lance, a nutritionist, surveys the dietary habits of a random sample of size ?=500 of young adults ages 20–39 in the United States. Apply the normal to find the probability that the number of individuals, X, in Lance's sample who regularly skip breakfast is greater than 123. You may find table of critical values helpful....
In Exercises 61 and 62, a binomial experiment is given. Determine whether you can use a normal distribution to approximate the binomial distribution. If you can, find the mean and standard deviation. If you cannot, explain why. 61. A survey of U.S. adults found that 75% support labeling legislation for genetically modified organisms (GMOs). You randomly select 20 U.S. adults and ask them whether they support labeling legislation for genetically modified organisms (GMOs). (Source: The Harris Poll) 62. A survey...
The United States Department of Agriculture (USDA) found that the proportion of young adults ages 20–39 who regularly skip eating breakfast is 0.238. Suppose that Lance, a nutritionist, surveys the dietary habits of a random sample of size n=500 of young adults ages 20–39 in the United States. Apply the central limit theorem for the binomial distribution to find the probability that the number of individuals, X, in Lance's sample who regularly skip breakfast is greater than 123. You may...
A survey of drivers in the United States found that 15% never use a cell phone while driving. Suppose that drivers arrive at random at an auto inspection station. If the inspector checks 10 drivers, what is the probability that at least one driver never uses a cell phone while driving? (Round your answer to the hundredth.) Suppose the inspector checks 1000 drivers. Use the normal approximation to the binomial distribution to find the approximate probability that at least 13%...
Favorite Sport A survey of U.S. adults found that 33% name professional football as their favorite sport. You randomly select 14 U.S. adults and ask them to name their favorite sport. Find the probability that the number who name professional football as their favorite sport is (a) exactly 8, (b) at most 4, and (c) fewer than 6.
