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%

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
