A boat capsized and sank in a lake. Based on an assumption of a mean weight of 138 Ib, the boat was rated to carry 60 passengers (so the load limit was 8,280 lb). After the boat sank, the assumed mean weight for similar boats was changed from 138 Ib to 175 lb. Complete parts a and b below. a. Assume that a similar boat is loaded with 60 passengers, and assume that the weights of people are normally distributed with a mean of 178.7 lb and a standard deviation of 38.6 lb. Find the probability that the boat is overloaded because the 60 passengers have a mean weight greater than 138 Ib. The probability is 1.0000 . (Round to four decimal places as needed.) b. The boat was later rated to carry only 16 passengers, and the load limit was changed to 2,800 lb. Find the probability that the boat is overloaded because the mean weight of the passengers is greater than 175 (so that their total weight is greater than the maximum capacity of 2,800 lb). The probability is (Round to four decimal places…
Suppose that the quarterly sales levels among health care information systems companies are approximately normally distributed with a mean of 12 million dollars and a standard deviation of 1.1 million dollars. One health care information systems company considers a quarter a "failure" if its sales level that quarter is in the bottom 20% of all quarterly sales levels. Determine the sales level (in millions of dollars) that is the cutoff between quarters that are considered "failures" by that company and quarters that are not. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.

Assume that a similar boat is loaded with 70 passengers, and assume that the weights of people are normally distributed with a mean of 182.9 lb and a standard deviation of 35.2 lb.

list five different things that are normally distributed. Examples that you can't use since I came up with them: Shoe size, middle finger length, oxygen level, electricity bill, wait times on line to pay at target. You must give the website where you found that they are normal for each one of them. 2) measure yourself and use the normal distribution to find out what percent of the population is less than use. What this means is that for one of the five things in 1) you need to make sure that you can find the mean and standard deviation. So an example would be: I found the oxygen level mean and standard deviation to be 98.3 and 1.1. My oxygen level is 98.9. Using the normal distribution calculator I found that 69.3% of the population has a lower measure of that. Help …. I don’t understand
