A scientist is growing single-crystal diamonds in the laboratory using a standard process and a new process. The scientist wants
to know which process causes the diamonds to grow faster. The mean growth rate for 20 diamonds grown using the standard
process is 0.7 micrometers per hour. The growth rate for 20 diamonds grown using the new process is 0.9 micrometers per
hour. The scientist uses simulations to get a randomization distribution to determine if the results happened by chance. The
randomization distribution is displayed in the histogram.
