The distribution of sample means will not be normal when it is grounded on small samples (n < 30) carefully chosen from a population that is not normal because if n < 30, you would the use the t distribution. Normal distribution would only be use if the sample size is large. Large in this case relies on the requirements for accuracy and the shape of the underlying population.

Mashcka [7]

Answer:

2 %

Step-by-step explanation:

Money borrowed, Principal, P = $ 700

time of investment, T = 3 years

Total interest paid, Simple interest, S.I = $ 42

Let the rate of interest is R.

Use the formula for simple interest.

$S.I. =\frac{P\times R\times T}{100}$

By substituting the values

$42 =\frac{700\times R\times 3}{100}$

4200 = 2100 R

R = 2 %

Thus, the rate of interest is 2%.
