The following data represent the responses (Y for yes and N for no) from a sample of 20 college students to the question "Do you currently own shares in any stocks?"
Y Y Y Y Y Y Y N N N
Y Y N Y Y N Y N Y NO
a. Determine the sample proportion, p, of college students who own shares of stock
b. If the population proportion is 0.30, determine the standard error of the proportion.
a. p=
(Type an integer or a decimal.)
b. 0,=
(Round to four decimal places as needed.)

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).
