Abank offers auto loans to qualified customers. the amount of the loans are normally distributed and have a known population standard deviation of 4 thousand dollars and an unknown population mean. a random sample of 22 loans is taken and gives a sample mean of 42 thousand dollars. find the margin of error for the confidence interval for the population mean with a 90% confidence level.

Drag and drop the answers into the boxes to complete this informal argument explaining how to derive the formula for the volume of a cone. since the volume of a cone is part of the volume of a cylinder with the same base and height, find the volume of a cylinder first. the base of a cylinder is a circle. the area of the base of a cylinder is , where r represents the radius. the volume of a cylinder can be described as slices of the base stacked upon each other. so, the volume of the cylinder can be found by multiplying the area of the circle by the height h of the cylinder. the volume of a cone is of the volume of a cylinder. therefore, the formula for the volume of a cone is 1/3 1/2 1/3πr^2h 1/2πr^2h πr^2h πr^2
