In this task, you’ll perform a re-randomization simulation to determine whether the difference of the sample means is statistica
lly significant enough to be attributed to the treatment.
Suppose you have 10 green bell peppers of various sizes from plants that have been part of an experimental study. The study involved treating the pepper plants with a nutrient supplement that would produce larger and heavier peppers. To test the supplement, only 5 out of the 10 peppers come from plants that were treated with the supplement. All 10 peppers were of the same variety and grown under similar conditions, other than the treatment applied to 5 of the pepper plants.
Your task is to examine the claim that the nutrient supplement yields larger peppers. You will base your conclusions on the weight data of the peppers. The table shows the weights of the 10 peppers, in ounces. (Note: Do not be concerned with which peppers received the treatment for now.) In this task, you’ll divide the data into two portions several times, take their means, and find the differences of the means. This process will create a set of differences of means that you can analyze to see whether the treatment was successful.

Answer:
Her net rate of pay in dollars per hour after the expense = $26
Step-by-step explanation:
Given:
Driver travels for 2 hours.
Speed = 60 miles per hour
Her car runs at the rate of 30 miles per gallon of gasoline.
She is paid $0.50 per mile.
Expenses is price of gasoline at the rate of $2.00 per gallon.
To find her net rate of pay in dollars per hour.
Solution:
In one hour the driver travels = 60 miles
For each mile she is paid = $0.50
<em>So, for 60 miles she will be paid = </em><em />
<em />
In a gallon of gasoline the car travels = 30 miles
<em>So, to travel 60 miles, the car would require = </em><em> gallons of gasoline</em>
1 gallon of gasoline cost = $2.00
<em>Expenses for 2 gallons of gasoline = </em><em />
<em />
So, in one hour she gets paid =$30 and her expenses for an hour drive = $4.
Thus, her net rate of pay in dollars per hour after the expense =
