Problem 75E

A pollster believes that 20% of the voters in a certain area favor a bond issue. If 64 voters are randomly sampled from the large number of voters in this area, approximate the probability that the sampled fraction of voters favoring the bond issue will not differ from the true fraction by more than .06.

Step-by-Step Solution:
Step 1 of 3

Chem 1010 9/6 – 9/8/2017 Class Notes Area  The area of a plane rectangle = length x width  Area of plane triangle = height x base / 2  Area enclosed by a plane circle = pi x radius 2(squared)  Three Dimensional objects have a surface area Volume, V In three dimensions we are more interests in volume. Volume is a measure of how much stuff you’ve got, a quantity of matter Liter is commonly used for fluids Liter was originally a base unit in the metric system Density Density is defined as mass / volume; d = m / V Water: 1.00 g per mL (1.00g/mL) –NEED TO KNOW- Temperature The volume increases as the temperature increases Celsius 100 C degrees=180 F degrees, 5 C=9 F degrees To Convert to F to C: calculate how many F degrees away from 32F Add or subtract 32
