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 =
Margin of error for 95%
Confidence interval =
Answer:
The new amount is 36
Step-by-step explanation:
we know that
100%+20%=120%
Let

by proportion
30/100%=x/120%
x=120*30/100=36
