Red : 5/12

Blue : 1/3

Green: 1/6

Yellow : 1/12

Answer:

The number of weeks required = 216 weeks

Step-by-step explanation:

Given that:

Margin of Error E = 200

Confidence interval = 95% = 0.95

Level of SIgnificance = 1 - C.I

= 1 - 0.95

= 0.05

Standard deviation = 1500

The Critical value for Z :

$Z_{\alpha/2} =Z_{0.05/2} \\ \\ = Z_{0.025} = 1.96$

The number of weeks( i.e the sample size (n) ) required is :

$n = (\dfrac{Z_{\alpha/2} \times \sigma}{E})^2$

$n = (\dfrac{1.96 \times 1500}{200})^2$

$n = (14.7)^2$

n = 216.09

n ≅ 216 weeks

Tresset [83]

Answer:

$\large \boxed{\$70.02}$

Step-by-step explanation:

The compound interest formula is

$A = P\left(1 + \dfrac{r}{n}\right)^{nt}$

Data:

P = 300

r = 2.12 % = 0.0212

t = 10 yr

n = 1 calculation per year

1. Accrued amount:

A = 300(1+ 0.0212)¹⁰

= 300 × 1.0212¹⁰

= 300 × 1.233 41

= 370.02

2. Interest

I = A - P = 370.02 - 300.00 = 70.02

$\text{The interest is $\large \boxed{\mathbf{\$70.02}}$}$
