Question

i represent the number of potholes on 35 randomly stretches of highway around a particular city. complete (b) construct a relative frequency distribution of the data. (c) using the results from part (b), what percentage of the stretches of highway have exactly 3 potholes? 14.3% (round to one decimal place as needed.) (d) using the results from part (b), what percentage of the stretches of highway have 5 or more potholes? (round to one decimal place as needed.)

Explanation:

Step1: Identify relevant relative frequencies

From the relative - frequency distribution, the relative frequency of 5 potholes is 0.114, of 6 potholes is 0.057, and of 7 potholes is 0.086.

Step2: Calculate the sum

We sum these relative frequencies: $0.114 + 0.057+0.086$.
$0.114+0.057 + 0.086=0.257$.

Step3: Convert to percentage

To convert the relative - frequency to a percentage, we multiply by 100.
$0.257\times100 = 25.7\%$

Answer:

25.7%
