What does deviation, or "deviate" mean? How can it help you remember the definition of *mean absolute deviation"? Deviate means to depart from, or go away. This can help remember that mean absolute deviations is the average distance away. STEPS TO To find the mean absolute deviation for a set of data, follow these steps: 1. Find the of the data set CALCULATE MAD. 2. Find the from each data point and the mean 3. Find the of those distances Practice folwing the steps to calculate the mean absolute deviation in the problem below. 1.

Question Help A boat capsized and sank in a lake. Based on an assumption of a mean weight of 137 lb, the boat was rated to carry 70 passengers (so the load limit was 9,590 lb). After the boat sank, the assumed mean weight for similar boats was changed from 137 lb to 171 lb. Complete parts a and b below. ts a. Assume that a similar boat is loaded with 70 passengers, and assume that the weights of people are normally distributed with a mean of 177.6 lb and a standard deviation of 39.1 lb. Find the probability that the boat is overloaded because the 70 passengers have a mean weight greater than 137 lb. The probability is (Round to four decimal places as needed.) b. The boat was later rated to carry only 17 passengers, and the load limit was changed to 2,907 Ib. Find the probability that the boat is overloaded because the mean weight of the passengers is greater than 171 (so that their total weight is greater than the maximum capacity of 2,907 lb). The probability is (Round to four decimal…
