Answer:
133
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
I = PRT/100 will do it.
I = Simple interest.
P = Principal ( Intial Amount invested).
R = Rate (as a percent).
T = time invested.
The above formula gives the amount of interest, If you want to find the interest rate knowing all the other values you have to solve for R:
I = PRT/100
100 I = PRT
R = 100I / PT is the formula .
Answer: (97.63, 99.77)
Step-by-step explanation:
Given the data:
99.6 99.7 97.9 98.6 97.7
Using calculator, we can obtain the mean and standard deviation of the sample data:
Mean(m) = 98.7
Standard deviation = 0.93
Sample size (n) = 5
Using the relation to find confidence interval :
Mean ± Zcrit * (s/√n)
Zcrit at 99% = 2.576
98.7 ± 2.576 * (0.93 / √5)
Lower limit : 98.7 - (2.576 * 0.4159086) = 97.6286194464 = 97.63 ( 1 decimal place)
Upper limit : 98.7 + (2.576 * 0.4159086) = 99.7713805536 = 99.77 ( 1 decimal place)
(97.6, 99.8)
