Answer:

Option A) 9604

Step-by-step explanation:

We are given the following in the question:

Confidence level = 95%

Standard error = 1%

$p = q = 0.5$

Formula for sample size:

$n = (z_{stat}\times \dfrac{p(1-p)}{\text{Standard error}})^2$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$n = (1.96\times \dfrac{0.5(1-0.5)}{0.01})^2 = 9604$

Thus, the sample size must be

Option A) 9604

Just need to solve c

Yuki888 [10]

Answer

1. 13,828

2. 516

Step-by-step explanation:

Ver 1 :

2s^3 + r - t

2s^3 = 24^3

24^3= 13,824

13,824 + r - t = 13,824 + (-3) - (-7)

13,824 + (-3) - (-7) = 13,828

Ver 2:

2s^3 + r - t

2s^3 = 2 x 4^3

2 x 4^3 = 512

512 + r - t = 512 + (-3) - (-7)

512 + (-3) - (-7) = 516
