What is a 96% confidence interval for the proportion of weight-lifting injuries in this age group that were accidental?

1 answer:

8 0

<span>A 96% confidence interval means that 96% of the time you can believe that the result will fall into a range of numbers. In the case of weight lifting this would mean that 96% of the time, the proportion of weight-lifting injuries were accidental would fall in between the two parameters set forth.</span>

Find the exact solution to the equation. Show your work for credit. (1 point) four to the power of quantity twelve minus four x

padilas [110]

4^(12-4x)=256 realize that 256 is 4^4 so we really have:

4^(12-4x)=4^4 taking the natural log of both sides

(12-4x)ln4=4ln4 dividing both sides by ln4

12-4x=4 subtract 12 from both sides

-4x=-8 divide both sides by -4

x=2
