Subtract $3$ from both sides.

2u=13-3

Subtract $3$ from $13$ to get $10$.

2u=10

Divide both sides by $2$.

u=\frac{10}{2}

Divide $10$ by $2$ to get $5$.

u=5

Engineers want to design seats in commercial aircraft so that they are wide enough to fit 95% of all males. (Accommodating 100% of males would require very wide seats that would be much too expensive.) Men have hip breadths that are normally distributed with a mean of 14.4 in. and a standard deviation of 1.2 in. Find P95. That is, find the hip breadth for men that separates the smallest 95% from the largest 5%.
