A histogram indicates that a normal distribution could be used as a model for the variable if the histogram is symmetric about its mean.
Given that the <span>relative frequency histogram represents the length of phone calls on george's cell phone during the month of september.
From the histogram, we can see that the histogram is left skewed, hence, the given histogram does not </span><span>indicate that a normal distribution could be used as a model for the variable.
Therefore, the answer is "No, because the histogram does not have the shape of a normal curve.

Answer:
- Jenny 1.75 miles, Keith 4.75 miles, Jonna 9.5 miles
Step-by-step explanation:
<u>Distance per person:</u>
- Jenny - x, Keith - y, Joanna - z
<u>Equation as per given:</u>
- y = x + 3
- z = 2y = 2(x + 3)
- x + y + z = 16
<u>Substitute and solve for x:</u>
- x + (x + 3) + 2(x + 3) = 16
- 2x + 3 + 2x + 6 = 16
- 4x = 7
- x = 7/4 = 1.75
Then
- y = 1.75 + 3 = 4.75
- z = 4.75*2 = 9.5
