In each of the following data sets, tell whether the outlier seems certain to be due to an error, or whether it could conceivably be correct. (a) the length of a rod is measured five times. the readings in centimeters are 48.5, 47.2, 4.91, 49.5, and 46.3.(b) the prices of five cars on dealer's lot are $25,000, $30,000, $42,000, $110,000 and $31,000.

in a the measure 4.91 can be considered an outlier.in b the value 110,000 can be correct

Step-by-step explanation:

a the errors of a measurement follow a normal distribution, if we find the mean and the corresponding variance we will find that the value 4.91 is very far from the mean, showing that is an error.in b the prices of cars can vary depending of the model of the cars, this prices are taken out of 5 different cars so it's possible for a car to be more expensive.
