You work for a company that manufactures suitcases in various
colors. You come up with what you think is a great idea for a new
color. Your boss is concerned that selling another color will
increase the manufacturing costs, so she wants to be 99% certain
that at least 15% of all the suitcases sold will be this new color
before agreeing to implement it permanently. Your company sells
your suitcases on multiple online sites and so you decide to
market the new color on one site only for one month as a test to
see what proportion of the suitcases sold are the new color.
When you report the results of the test to your boss you make a
Type I error.
A statistics teacher wants to see if there is any
difference in the performance of students on the final
exam if she gives them orange jelly beans before the
exam. She has a theory that orange jelly beans will
change the results, but she isn't sure in which
direction. She knows that the population mean score
on the exam when students do not have orange jelly
beans is 85 and that exam scores have an
approximately symmetric distribution. She gives
orange jelly beans to 25 randomly selected students
and finds that these students had a sample mean
score of 88 with a sample standard deviation of 5. She
wants to have 99% confidence in her result.
