Question

Every 17 years, swarms of cicadas emerge from the ground in the eastern United States, live for about six weeks, then die. (There are several “broods,” so we experience cicada eruptions more often than every 17 years.) There are so many cicadas that their dead bodies can serve as fertilizer and increase plant growth. In an experiment, a researcher added 10 cicadas under some plants in a natural plot of American bellflowers in a forest, leaving other plants undisturbed. One of the response variables was the size of seeds produced by the plants. The table contains data (seed mass in milligrams) for 39 cicada plants and 33 undisturbed (control) plants.

Include A picture of both of the histograms

Now, calculate the appropriate numerical measures used to compare the distributions. Match your answers, and mark the inappropriate measures as not relevant.

Cicada plants' ?‑scores	Control plants' mean
Control plants' ?‑scores	Cicada plants' standard deviation
Cicada plants' mean	Control plants' standard deviation

Answer 1

Usining Minitab:

Insert Histogram Data Set in worksheet

Go to Graph > Histogram > Simple:

Click “OK”:

Click OK.

Numerical measures:

inappropriate measures as not relevant. are:

Cicada plants' ?‑scores and Control plants' ?‑scores.

Hope this will be helpful. Thanks and God Bless You :)
