1. Particles are discharged from a radioactive source according to a Poisson process, with a= 1.2 per minute. Suppose that every week, at twenty randomly selected times, the number of particles discharged over a five-mimute period will be recorded. A. What question are we asking of each five-minute period? (What size? Yes or No? How many?) B. Every week, the manager records the number of particles discharged in each of the 20 randomly selected five-minute periods and then computes the total. What is the probability that the total number of particles discharged in the sample is at least 135? C. What is the probability that the average of a sample (of n= 20 five-minute intervals) will be at least 6.75? (HINT: Convert the average to a total.) D. What is the probability that a sample average (from n- 20 five-minute intervals) will be between 5.82 and 6.27? Radioactive Atom Energy Radiation Particle

The control department of a light bulb manufacturer randomly picks 4400 light bulbs from the production lot every week. The records show that, when there is no malfunction, the defect rate in the manufacturing process (due to imperfections in the material used) is 1%. When 1.25%o or more of the light bulbs in the sample of 4400 are defective, the control unit calls repair technicians for service. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p, where p is the proportion of defective light bulbs in a sample of 4400 when there is no malfunction. (b) Find the standard deviation of p. (c) Compute an approximation for P(p N 0.0125), which is the probability that the service technicians will be called even though the system is functioning properly. Round your answer to four decimal places.
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 her 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 312 trials, the touch therapists were correct 151 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? (Type an integer or a decimal. Do not round.) b. Using Emily's sample results, what is the best point estimate of the therapists' success rate? (Round to three decimal places as needed.) c. Using Emily's sample results, construct a 90% confidence interval estimate of the proportion of correct responses made by touch therapists.
A researcher wants to know whether children with ADHD tend to watch more TV than children who are not diagnosed with the disorder. To examine this, a researcher obtains a sample of n = 36 children (ages 8 to 12 years) who have been diagnosed with ADHD. Each child is asked to keep a journal recording how much time each day is spent watching TV. The average for the sample is M = 4.9 hours/day. Assume that the average TV-watching time for the general population of 8-to-12-year-old children is µ = 4.1 hours/day with σ = 1.8. Is ADHD in children associated with an increased amount of TV-watching?

7. Many businesses have music piped into the work areas to improve the environment. At a company an experiment is performed to compare different types of music. Three types of music - country, rock, and classical – are tried, each on four randomly selected days. Each day the productivity, measured by the number of items produced, is recorded. The results appear below: Country Rock Classical 857 791 824 801 753 847 795 781 881 842 776 865 1.1. Is there a significant difference between the three types of music? Use a =.05. 7.2 Solve using Analysis of Variance. 7.3 Which type of music seem to be best? 7.4 Which type of music seem to be worst?
