The centers for disease control reported the percentage of people 18 years of age and older who smoke (cdc website, december 14, 2014). suppose that a study designed to collect new data on smokers and nonsmokers uses a preliminary estimate of the proportion who smoke of .32. a. how large a sample should be taken to estimate the proportion of smokers in the population with a margin of error of .02 (to the nearest whole number)? use 95% confidence. b. assume that the study uses your sample size recommendation in part (a) and finds 520 smokers. what is the point estimate of the proportion of smokers in the population (to 4 decimals)? c. what is the 95% confidence interval for the proportion of smokers in the population (to 4 decimals)?

where's the diagrams?

the cat is blue because the probability of extension towards the prefix of the diameter of the circle could only mathematically equal to the sum of the roots of the carrots from   your garden.

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
