N2004, the general social survey (which uses a method similar to simple random sampling) asked, "do you consider yourself athletic? " for this question, 255 people said that that they did out of 2373 randomly selected people. what is the standard error of the confidence interval?

Answer-

The standard error of the confidence interval is 0.63%

Solution-

Given,

n = 2373 (sample size)

x = 255 (number of people who bought)

The mean of the sample M will be,

Then the standard error SE will be,

Therefore, the standard error of the confidence interval is 0.63%

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
