Answer:
1568
Step-by-step explanation:
The computation of the minimum sample size is shown below:
Given that
Error E = 11
The population standard deviation
=217
Confidence level 1-α = 95%
Now following formula should be used
n > (Zalpha ÷ 2 × sigma ÷ E)^2
As we know that
Zalpha ÷ 2= 1.96
Now the sample size is
n> (1.96 × 202 ÷ 10)^2
= 1568

Answer:
$98.15
Step-by-step explanation:
2005 is 15 years after 1990. Using the formula we find ...
c(15) = 63·1.03^15 ≈ 63·1.55797
c(15) ≈ 98.152
An ounce of the chemical costs about $98.15 in 2005.
