In this question we have to find the effect of doubling principal, rate or time .
First we have to check the formula which is
As we see that interest is the product of principal, rate and time. So if any of these three doubles, that is if any of these three is twice of the original value, the interest gets doubled.
SO the correct option is C.
The 90% confidence interval for the true difference between the population proportions is [ - 0.0908, - 0.0092]
Given,
= 731
= 644
= 0.33
= 0.28
z score for 90% confidence interval = 1.645
Here, the confidence interval formula :
( ) ± z
Substituting the values, we get
(0.33 - 0.28) ± 1.645
= 0.05 ± 1.645
= 0.05 ± 1.645
= 0.05 ± 1.645 × 0.0248093914
= 0. 05 ± 0.0408114489
Confidence interval:
- 0.05 - 0.0408114489 = - 0.0908114489 ≈ - 0.0908
- 0.05 + 0.0408114489 = - 0.0091885511 ≈ - 0.0092
The confidence interval for the true difference between the population proportions is [ - 0.0908, - 0.0092]
