- The age of children in kindergarten on the first day of school is uniformly distributed between 4.88 and 5.94 years old. A first time kindergarten child is selected at random. Round answers to 4 decimal places if possible. If such a child is at the 87th percentile, how old is that child? ____ years old..59. Potatoes. A high-quality product is one that is consistent and has very little variability in its characteristics. Controlling variability can be more difficult with agricultural products than with those that are manufactured. The following table gives the weights, in ounces, of the 25 potatoes sold in a 10-pound bag. (a) Summarize the data graphically and numerically. Give reasons for the methods you chose to use in your summaries. (b) Do you think that your numerical summaries do an effective job of describing these data? Why or why not? (c) There appear to be two distinct clusters of weights for these potatoes. Divide the sample into two subsamples based on the clustering. Give the mean and standard deviation for each subsample. Do you think that this way of summarizing these data is better than a numerical summary that uses all the data as a single sample? Give a reason for your answer.Using 68-95-99.7% rule to indicate quantities In a study of facial behavior, people in the control group are timed for eye contact in a 5-minute period. Their times are normally distributed with a mean of 183.0 seconds and a standard of 55.0 seconds. What percent of times will between 73 and 293 seconds? what percent of times will be over 238 seconds? Suppose that 800 people were assigned to this control group. How many people will be with time over 238?

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 o = 8.00 ml/kg for the distribution of blood plasma.
