Step-by-step explanation:
Let Shriya's current age b <em>x</em><em>.</em><em> </em>Arjun's current age will be <em>2</em><em>x</em>.
5 years ago, Arjun's age was <em>2</em><em>x</em><em>-</em><em>5</em><em> </em>and Shriya's age was <em>x</em><em>-</em><em>5</em><em>.</em>
Since Arjun's age was 3 times Shriya's age 5 years ago,
<em>2</em><em>x</em><em>-</em><em>5</em><em> </em>= <em>3</em><em> </em><em>(</em><em>x</em><em>-</em><em>5</em><em>)</em>
<em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>0</em>
<em>2</em><em>x</em><em> </em><em>=</em><em> </em><em>2</em><em>0</em>

A 95% confidence interval for the proportion of non-fatal accidents involving a distracted driver using some kind of electronic device is 62.5%<x<71.61%
The 95% confidence interval for the proportion is expressed according to the formula;

p is the proportion = 268/400 = 0.67
z is the 95% z-score = 1.96
n is the sample space = 400
Substitute the given parameters into the formula to have:

Hence a 95% confidence interval for the proportion of non-fatal accidents involving a distracted driver using some kind of electronic device is 62.5%<x<71.61%
