Answer:
25.4, 28.6
Step-by-step explanation:
Given parameters
sample size, n = 24
sample mean, X = 27
population standard deviation, s = 3
critical value, Zα/2, where α = 0.01
99% confidence Interval, CI, is given as follows
CI = X ± Zα/2 × (s/√n)
Zα/2 = Z0.01/2 = Z0.005 = 2.576
CI = 27 ± 2.576 × (3/√24)
= (25.42 ,28.57)
Step-by-step explanation:
Principal:- $5000
Rate= 8%
Time = 9 years
Interest = P×R×T/100
= 500×8×9/100
= 5×8×9
= 40×9
= 360
Hence, Interest = $360.
