10 af 50 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.

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.
