In a prior sample of U.S. adults, the Center for Disease Control (CDC), found that 8% of the people in this sample had pinworm b
kow [346]

Answer: a) 453  b) 1537

Step-by-step explanation:

As per given , we have

Margin of error : E= 0.025

Critical value for 95% confidence interval : z_{\alpha/2}=1.96

a) The prior estimate of population proportion : p=0.08

Required sample size :-

n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.08(1-0.08)(\dfrac{1.96}{0.025})^2\\\\=452.386816\approx453

The minimum sample size is 453 U.S. adults.

b) Since the prior estimate of population proportion is not available , so we take p= 0.5

Required sample size :-

n=0.5(1-0.5)(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.25(\dfrac{1.96}{0.025})^2\\\\=1536.64\approx1537

The minimum sample size is 1537 U.S. adults.

Find measure of side AB round to nearest tenth
vova2212 [387]
Use:

|AB|^2=|AC|^2+|BC|^2-2|AC||BC|\cos(m\angle ACB)

We have:

|AC|=13;\ |BC|=29;\ m\angle ACB=41^o

\cos41^o\approx0.7547

substitute:

|AB|^2=13^2+29^6-2\cdot13\cdot29\cdot0.7547\\\\|AB|^2=440.9562\\\\|AB|\approx21

Please help im timed <br> how would you solve 17=w/4?
max2010maxim [7]

Answer:

Solution for 17=w-4 equation:

17=w-4

We simplify the equation to the form, which is simple to understand

17=w-4

We move all terms containing w to the left and all other terms to the right.

-1w=-4-17

We simplify the left and right sides of the equation.

-1w=-21

We divide both sides of the equation by -01 to get w.

w=21
