Tall Dutch Men: Part A Use a z-table such as https://www.math.arizona.edu/~rsims/ma464/standardnormaltable.pdf or an online calculator such as  http://onlinestatbook.com/2/calculators/normal_dist.html to answer the following question: Dutch men are famously perceived as being tall.  In a 2014 survey it was found that the mean adult male height in the Netherlands was 182.5 cm with a standard deviation of 7.4 cm and that the heights followed a normal distribution. What proportion of the population of adult males in the Netherlands would be between the heights of 178.8 cm and 186.2 cm?  Express your answer as a percentage rounded off to 1 decimal place.   Tall Dutch Men: Part B Which of the following normal distribution curves would best represent the probability calculated in the previous question?     normal distribution a     normal distribution b     normal distribution c     normal distribution d      normal distribution e    normal distribution f…

QUESTION 1 The U.S. Mint produces approximately 13 billion pennies a year. A random sample (n-800) of pennies were collected and their minted years were recorded. The output, histogram, box-plot, and QQ plot for the distribution of the years of production for the pennies can be found on the attached document.
