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)
Answer:
See Below
Step-by-step explanation:
Ok, simplify 0.08/4
0.08/4 =1/50
1/50 x 8000 =160
So now you got ![\frac{160}{[1-(1+\frac{0.08}{4})^{-4(8)}] }](https://tex.z-dn.net/?f=%5Cfrac%7B160%7D%7B%5B1-%281%2B%5Cfrac%7B0.08%7D%7B4%7D%29%5E%7B-4%288%29%7D%5D%20%20%7D)
Now simplify the bottom
0.08 / 4 =1/50
1/50 + 50/50 = 51/50
50/50 - 51/50 = -1/50
-1 /50 ^ (4 x 8) = -1/50 ^32 = 4.294967296 x 10^-55
4.29 x 10^-55
Please let me know if incorrect.
