I think the answer is Letter C - 0.032.

Given: p - 0.1; n - 90
Required: standard deviation of the sample proportion
Solution: To get the standard deviation of the sample proportion, we will use this formula - std = √p (1 - p) / n Replace the variables with the given values, then simplify.
   std = √0.1 (1 - 0.1) / 90
   std = √0.09 / 90
   std = √0.001
   std = 0.032

A sum of rs 400 is lent for 3 yrs at the rate of 6% per annum. Find the interest.
Nimfa-mama [501]
Interest is equal to rs 72

Simple Interest is computed by multiplying the principal to the interest rate and the time.

I = P * r * t

Principal = rs 400
Interest rate = 6%
Term / time = 3 yrs

I = 400 * 6% * 3
I = 72   the total interest that must be paid in 3 yrs.
