Suppose 51 % of the banks in Switzerland are private organizations.

noname [10]

Answer:

0.9689

Step-by-step explanation:

Given:

banks in Switzerland are private organizations, p = 51% = 0.51

Sample size, n = 544 banks

To find:

Probability (the sample proportion of private banks will be greater than 47%)

Now,

Mean of the sample, μ = np = 544 × 0.51 = 277.44

$\bar{x}$ = 544 × 0.47 = 255.68

Standard deviation = $\sqrt{np(1-p)}$

Standard deviation = $\sqrt{544\times0.51(1-0.51)}$

Standard deviation = 11.6595

Now,

$P(\bar{x}\geq 47\%)$

= $P(z\geq \frac{\bar{x}-\mu}{\sigma})$

= $1- P(z\leq \frac{\bar{x}-\mu}{\sigma})$

= $1- P(z\leq \frac{255.68-277.44}{11.6595})$

= $1- P(z\leq -1.8662)$

Now, from standard z value table, we get

= 1 - 0.031021

= 0.9689

I think it’s 18 and I will explain how I got that

Explanation: so first I added all the marbles she took out to see the total she took out which was 50 and if she did it 90 times I need to see how much time 50 she did it more and that was so 90 divided by 50 is 1.8 and that times 10 (times because we want to see how many times the red marble would come out) and that’s 18
