Answer:
-2.508
Step-by-step explanation:
From the given information:
The null hypothesis and the alternative hypothesis can be computed as:
![H_o : \mu = 5](https://tex.z-dn.net/?f=H_o%20%3A%20%5Cmu%20%3D%205)
![H_1: \mu < 5](https://tex.z-dn.net/?f=H_1%3A%20%5Cmu%20%3C%20%205)
This is a left-tailed test.
The sample size n = 23
Then, the degree of freedom df = n - 1
df = 23 - 1
df = 22
The level of significance ∝ = 0.01
Using the student t-table to determine the critical value;
= -2.508 (since it is left tailed)
Answer: Radha pays $387.50 more interest than Fabina
<u>Step-by-step explanation:</u>
<u>Fabina</u>
Simple Interest: I = P × r × t
= 12500 × 0.10 × 3
= $3750.00
<u>Radha</u>
![\text{Compound Interest:}\ A = P(1+r)^t\\.\qquad \qquad \qquad \qquad \qquad =12500(1+0.10)^3\\.\qquad \qquad \qquad \qquad \qquad =12500(1.10)^3\\.\qquad \qquad \qquad \qquad \qquad =16637.50](https://tex.z-dn.net/?f=%5Ctext%7BCompound%20Interest%3A%7D%5C%20A%20%3D%20P%281%2Br%29%5Et%5C%5C.%5Cqquad%20%5Cqquad%20%5Cqquad%20%5Cqquad%20%5Cqquad%20%3D12500%281%2B0.10%29%5E3%5C%5C.%5Cqquad%20%5Cqquad%20%5Cqquad%20%5Cqquad%20%5Cqquad%20%3D12500%281.10%29%5E3%5C%5C.%5Cqquad%20%5Cqquad%20%5Cqquad%20%5Cqquad%20%5Cqquad%20%3D16637.50)
16637.50 - 12500 = $4137.50
4137.50 - 3750.00 = $387.50
