Suppose that 12% of the population of the U.S. is left-handed. If a random sample of 130 people from the U.S. is chosen, approximate the probability that at most 14 are left-handed. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps.

Suppose that about 9.2% of the population is left-handed. A 200-seat school auditorium has been built with 15 “lefty seats,” seats that have the built-in desk on the left rather than the right arm of the chair. In a class of 120 students, what is the probability that there will not be enough seats for the left-handed students? Explain how you arrived at your answer.

We will be using Excel to simulate the number of left-handed people in a particular sample. Left-handed people make up about 10% of the population. We will randomly pick numbers between 1 and 10, where 1 represents a left-handed person and 2 - 10 represents a right-handed person. This should result in about 10% of our sample being left-handed. Please note there are five parts to this question. 1. Create a pie graph in Excel to show the proportion of...

Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 256 feet and a standard deviation of 45 feet. Use your graphing calculator to answer the following questions. Write your answers in percent form.
