Answer:

Step-by-step explanation:

Given that a part of a study of the treatment of anemia in cattle, researchers measured the concentration of selenium in the blood of 36 cows who had been given a dietary supplement of selenium (2 mg/day) for one year.

If x is the selenium concentration then

X has mean= 6.21 mg/dl

and std dev = 1.84

Sample size n = 36

std error of sample = $\frac{1.84}{\sqrt{36} } \\=0.307$

Margin of error for 95%

$1.96(0.307)=0.602$

Confidence interval = $(6.21-0.605, 6.21+0.605)\\= (5.605, 6.815)$
