The average American consumes a mean of 84 grams of sugar with a standard deviation of 30 grams. How many grams of sugar do 15% Americans consume more than? Assume that amount of sugar American's consume is normally distributed. Represent the probability with a graph.
Homework Answers
Given that,
P(Z > 1.04) = 0.15
z = 1.04
Using z-score formula,
x = z * 
+ 
x = 1.04 * 30 + 84 = 115.2
Answer = 115.2 grams

A recent survey revealed that an American's Christmas spending averaged $830
A recent survey revealed that an American's Christmas spending averaged $830. Use this as the population mean American's Christmas spending. Suppose Americans' Christmas spending is normally distributed with a standard deviation of $220. A random sample of size 100 is selected from the population of American consumers. What is the probability that the sample mean spending is no more than $840?
