What is the difference between normalcdf and normalpdf on ti84 calculator?
Looking to do this with calculator do I use the normalcdf ? I came up with fro the first one .1642 2.) Each American uses 650 pounds of paper a year. Suppose that the distribution is approximately normal with a population standard deviation of 153.5 pounds. Find the probability that a randomly selected American uses: a.) More than 800 pounds a year-normalcdf( b.) Less than 400 pounds a year c.) Between 500 and 700 pounds a year 3.) The average...

PLEASE SHOW THE CALCULATOR TI84 WAY OF DOING THIS. OR SHOW WORK Each year the US Environmental Protection Agency (EPA) releases fuel economy data on cars manufactured in that year. Below are summary statistics on fuel efficiency (in miles/gallon) from random samples of cars with manual and automatic transmissions manufactured in 2012. Do these data provide strong evidence of a difference between the average fuel efficiency of cars with manual and automatic transmissions in terms of their average city mileage?...
