maria [59]

Answer:

the probability of observing 27 or more students 0.818

Step-by-step explanation:

given data

sample n = 28 students

population = 93%

to find out

the probability of observing 27 or more students

solution

we will find Z value for CI 93%  

from z table we get Z is 1.812 for Cl 93%

so P(27 ≤ Z ≤ 28)

we know Z = 0.182

= 1 - 0.182

= 0.818

the probability of observing 27 or more students 0.818

Find the amount in a account where $200 is invested at 3.5% compounded quarterly for a period of 3 years.
AlexFokin [52]

The amount after 3 years would be $221.74

<u>Explanation:</u>

Given:

Principal, P = $200

Rate of interest, r = 3.5%

Time, t = 3 years

Amount, A = ?

We know:

A = P(1+\frac{r}{100})^t

Substituting the value we get:

A = 200(1+\frac{3.5}{100} )^3\\\\A = 200 X 1.108\\\\A = 221.74

Therefore, the amount after 3 years would be $221.74
