burban Families Watched An Average Of μ = 60 Minutes Of Television Each Day. Assuming That The Distribution Of Television-watching Times Is Normal With A Standard Deviation Of σ = 25 Minutes, Find Each Of The Following Proportions. A. What Proportion Of 2-year-old Children Watch ... This problem has been solved! See the answer A recent report indicates that 2-year-old children from well-educated suburban families watched an average of μ = 60 minutes of television each day. Assuming that the distribution of television-watching times is normal with a standard deviation of σ = 25 minutes, find each of the following proportions. a. What proportion of 2-year-old children watch more than 2 hours of television each day? b. What proportion of 2-year-old children watch less than 30 minutes a day?

J 1 IQ scores of people around the World are normally distributed, with a mean of 100 and a standard deviation of 15. A genius is someone with an IQ greater than or equal to 140. What percent of the population is considered genius? The Weights of 100 remote control cars at a competition are approximately normally distributed. The average weight is 3.2 kg, with a standard deviation of 0.4 kg. How many remote control cars would be disqualified if it were against the rules to have a car with a weight of more than 4 kg or less than 2.4 kg? A car is said to be in the 90th percentile. How much does it weigh? Using the Statistics for 42 Countries, choose one variable to collect for each of the countries. You may use the data you have collected in the past. Calculate the percentile of the country for the collected variable by first calculating the mean, standard deviation and z-score. If you sort the countries by the variable from highest to lowest, what percent of the countries are below the…

5.58 The concentration of mercury in a lake has been monitored for a number of years. Measurements taken on a weekly basis yielded an average of 1.20 mg/m (milligrams per cubic meter) with a standard deviation of .32 mg/m. Following an accident at a smelter on the shore of the lake, 15 measurements produced the following mercury concentrations. 1.60 1.77 1.61 1.08 1.07 1.79 1.34 1.07 1.45 1.59 1.43 2.07 1.16 0.85 2.11 ES ABOUT POPULATION CENTRAL VALUES a. Give a point estimate of the mean mercury concentration after the accident. b. Construct a 95% confidence interval on the mean mereury concentration after the accident. Interpret this interval. c. Is there sufficient evidence that the mean mercury concentration has increased since the accident? Use a = .05. d. Assuming that the standard deviation of the mercury concentration is .32 mg/m. calculate the power of the test to detect mercury concentrations of 1.28, 1.32. 1.36, and 1.40.
