Determine whether the following procedure results in a binomial distribution or a distribution that can be treated as binomial (by applying the 5% guideline for cumbersome calculations). If it is not binomial and cannot be treated as binomial, identify at least one requirement that isnot satisfied.In a survey of a large country, 3300 different households were randomly selected without replacement, and respondents were asked whether the household had a smart TV. Answers of "yes" and "no" were recorded.CChoose the correct answer below.O A. It is binomial or can be treated as binomial.O B. It is not binomial because the probability of success does not remain the same in all trials.O C. It is not binomial because the selections are not independent. (The 5% guideline for cumbersome calculations should not be used.)O D. It is not binomial because there are more than two mutually exclusive outcomes for each trial.

In 1996, McDonald's estimated that 10% of all American workers had worked at McDonald's at one point in their career (www.businessinsider.co m). Assume that 6 American workers are randomly selected, and that this can be modeled as a binomial distribution. Would it be unusual for 4 or more of the 6 workers to have worked at McDonald's? Why or why not? (SENTENCES - BE SPECIFIC) T TTArial v 3 (12pt) v T- := - E - 只i Y
n studies for a medication, 15 percent of patients gained weight as a side effect. Suppose 541 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that a) exactly 82 patients will gain weight as a side effect. (b) no more than 82 patients will gain weight as a side effect. (c) at least 92 patients will gain weight as a side effect. What does this result suggest?

According to a study by the National Institute on Alcohol Abuse and Alcoholism, 19% of college students between the ages of 18 and 24 meet the criteria for alcohol abuse or dependence. Coker University wants to determine whether it has a lower, average, or higher rate of alcohol abuse than the national average. A random sample of 48 students is selected, and evaluated for signs of alcohol abuse or dependence. a. Identify n for the binomial experiment. b. Identify p for the binomial experiment. c. Find the probability that 2 or fewer of the students in the sample exhibit signs of alcohol abuse or dependence. Round your answer to 4 decimal places. d. If 2 out of the sample of 48 exhibited signs of alcohol abuse or dependence, would Coker University be justified in claiming that an unusually low percentage of our students exhibit signs of alcohol abuse or dependence?…

Please show the full solution and proper notation and terminology. 3. A data firm records a large amount of data. Historically, 2% of the pages of data recorded by the firm contain errors. A sample of 300 pages is randomly selected. What is the probability that a. What is the probability that fewer than 5 pages contain errors? b. What is the probability that none of the pages contain errors? c. This binomial distribution can be approximated using Poisson if n>20 and np7. If this condition is true, the for Poisson distribution is equal to the mean for the binomial. Evaluate (a) using Poisson approximation if applicable. thanks.
Determine whether the following procedure results in a binomial distribution or a distribution that can be treated as binomial (by applying the 5% guideline for cumbersome calculations). If it is not binomial and cannot be treated as binomial, identify at least one requirement that is not satisfied. The Senate members of the 116th Congress include 75 males and 25 females. Ten different senators are randomly selected without replacement, and the gender of each selected senator is recorded. Choose the correct answer below. O A. It is binomial or can be treated as binomial. O B. It is not binomial because the selections are not independent. (The 5% guideline for cumbersome calculations should not be used.) O C. It is not binomial because there are more than two mutually exclusive outcomes for each trial. O D. It is not binomial because the experiment is not performed a fixed number of times.
The U.S. Health Department reported that 40% of households had both a wireless phone and a landline. Assume that in a simple random sample of 300 households, 105 are found to have both services. With this information answer the following questions: What is the population proportion, π? What is the sample proportion, p? What is the standard error of the sample proportion? In the sampling distribution of the proportion, what is the probability that a sample of this size would result in a sample proportion at least 35%?

If it is not binomial and cannot be treated as binomial, identify at least one requirement that is not satisfied. The House members of the 116th Congress include 309 males and 126 females. Forty different representatives are randomly selected without replacement, and the gender of each selected representative is recorded. Choose the correct answer below. A. It is binomial or can be treated as binomial. B. It is not binomial because there are more than two mutually exclusive outcomes for each trial. C.

Suppose that 20% of the residents in a certain state suppor an increase in the property tax. An opinion poll will randomly sample 400 state residents and will then compute the proportion in the sample that support a property tax increase. How likely is the resulting sample proportion to be within 0.04 of the true proportion (i.e., between 0.16 and 0.24)? (Hint: Use the sampling distribution of the sample proportion in this case.) A. O It is certain that the resulting sample proportion will be within 0.04 of the true proportion. B. There is roughly a 99.7% chance that the resulting sample proportion will be within 0.04 of the true proportion. C. There is roughly a 95% chance that the resulting sample proportion will be within 0.04 of the true proportion. D. O There is roughly a 68% chance that the resulting sample proportion will be within 0.04 of the true proportion.
A recent study showed that 71% of adults need some type of corrective lens (glasses or contacts). A. If I grab a 6 random people what is the probability that fewer than 4 need corrective lenses? B. If I take a random sample of 2000 people what is the mean and standard deviation of the number of people who need corrective lens? C. Use the normal approximation to the binomial to find the probability that I get 1375 or fewer people who need corrective lenses out of a random sample of 2000. Illustrate what you are finding on a sketch of the normal curve and show your work.
