- A normal distribution has a mean of 100 and a standard deviation of 2. If 69,146% of the data are less than X what is the value of x?In a county male height is normally distributed with a mean of 175 cmand a standard deviation of 6 cm. What percentage of males have aheight between 168 cm and 172 cm. Sketch the Graph too.The number of hurricanes coming within 250 miles is modeled by Polsson distribution with meanz per year. Find the mean and the variance of the time between successive hurricanes.
- find standard deviation if range is 3.The length of 100 movies was recorded and the standard deviation was computed. This would be a: 1.Parameter 2.The same as the variance 3.measure of center 4. statisticFind the probability that a randomly selected year of rain in Sydney, Australia has a yearly rainfall of 130.8 mm or more. where the mean is 137mn and the standard deviation is 69mn.
- Naini, Cobourne, McDonald and Donaldson (2008) reported that a specific ratio of height to face length of 1 to 8.5 tended to be rated as most attractive—almost exactly what Da Vinci’s idealized Vitruvian Man, predicts as “perfection” in the human form. For this study, we want to see if there is a relationship between a person’s height and head circumference. We get a random sample of 40 people and measure both their height and their head size to the nearest centimeter. What test should you use and why?With a mean of 110 and standard dev. of 15, find the 3 unique deviations to the left and right of the mean.The birth weights of children born in the United States are normally distributed and have a ?=7.5μ=7.5 pounds. How does the median birth weight compare to the average birth weight?
- How standard deviation affects the power?Explain the effect of the standard deviation on power?Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 44 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.50 ml/kg for the distribution of blood plasma. When finding an 99% confidence interval, what is the critical value for confidence level? (Give your answer to two decimal places.) zc = (a) Find a 99% confidence interval for the population mean blood plasma volume in male firefighters. What is the margin of error? (Round your answers to two decimal places.) lower limit upper limit margin of error
