Mathematics: Dr. Nunez wants to estimate the average lung capacity of adults in her state. She plans on taking a sample of n adults to construct a 99% confidence interval for the mean lung capacity. She wants the margin of error to be no more than 100 mL. She s willing to use o = 300 mL as an estimate for the population standard deviation. Which of these is the smallest approximate sample size required to obtain the desired margin of error? Choose 1 35 adults B 45 adults 50 adults 55 adults

Option A. 10

Step-by-step explanation:

we know that

Applying the Intersecting Secants Theorem

QS*RS=CS*TS

substitute the values

(11x-1+8)*(8)=(9+7)*(9)

solve for x

(11x+7)*(8)=(16)*(9)

88x+56=144

88x=144-56

88x=88

x=1

Find the measure of QR

QR=11x-1=11(1)-1=10
