<h3>How to determine the number?</h3>

The statement is given as:

280 tenths + 19 thousandths

Rewrite the terms of the expression as fractions

Evaluate the quotients

28.0 + 0.019

She wishes to estimate the proportion of horses with enteroliths who are fed at least two flakes of alfalfa per day. In a sample

pogonyaev

Answer:

0.0594.

Step-by-step explanation:

The standard error of a proportion p, in a sample of size n, is given by:

$SE_{p} = \sqrt{\frac{p(1-p)}{n}}$

In a sample of 62 horses with enteroliths, she finds 42 are fed two or more flakes of alfalfa.

This means that $n = 62, p = \frac{42}{62} = 0.6774$

$SE_{p} = \sqrt{\frac{p(1-p)}{n}}$

$SE_{p} = \sqrt{\frac{0.6774*0.3226}{62}} = 0.0594$

So the correct answer is:

0.0594.
