Buchral, a manufacturer of ceramic tiles, reports on average 3.9 job-related accidents per year. Accident categories include trip, fall, struck by equipment, transportation, and handling. The number of accidents is approximately Poisson.a. What is the probability that more than one accident occurs per year? Please include at least three decimal places in your answer.Probability:h. Suppose thar 8.6 years are randomly selected. What is the expected number of accidents in this time period?Expected number:c. What is the standard deviation of the number of accidents in 8.6 years?Standard deviation:44d. What is the probability that exactly 31 accidents occur in 8.6 years? Include at least 3 decimal places in your answer. Please include at least three decimal places in your answer.

What is the significance of the mean of a probability distribution? Choose the correct answer below. O A. It represents the most likely possible outcome. B. It is the expected value of a discrete random variable. OC. It can never be negative. OD. It gives information about how the outcomes vary.
You may need to use the appropriate appendix table or technology to answer this question. A market research firm conducts telephone surveys with a 26% historical response rate. What is the probability that in a new sample of 600 telephone numbers, at least 150 individuals will cooperate and respond to the questions? In other words, what is the probability that the sample proportion will be at least 150 600 = 0.25? Step 1 Recall that a sampling distribution of p is a discrete probability distribution but can be approximated by a normal distribution when np ≥ 5 and n(1 − p) ≥ 5, where n is the sample size and p is the population proportion. Let p be the population proportion of people who respond to questions in telephone surveys. Here, it is given that 26% of people respond to questions in telephone surveys. Converting this percentage to a proportion gives p = . There is a sample of 600 telephone numbers, so n = .
