45000(1-4.5%) to the 12th power would be 25897 people
Let's rewrite the given sequence :1/3, 1, 5/3, 7/3 . Notice that 1 =3/3, then
1/3, 3/3, 5/3, 7/3,...We also notice that the common difference d is equal to:
3/3 - 1/3 = 2/3 and 5/3 - 3/3 = 2/3 & 7/3 - 5/3 = 2/3
Hence this sequence is NOT A GEOMETRIC PROGRESSION but an ARITHMETIC PROGRESSION,instead with d = 2/3
Answer: a. 19.200 to 20.800
Step-by-step explanation:
Formula to find the confidence interval
:-

, where n is the sample size
= Population standard deviation.
= Sample mean
= Two tailed z-value for significance level of
.
Given : Confidence level = 95.44% = 0.9544
Significance level = 
Using standard normal z-value table ,
Two tailed z-value for Significance level of 0.0456 :

Also,
n=144

Then, the required 95.44% confidence interval for the population mean :-

Hence, the 95.44% confidence interval for the population mean is <u>19.200 to 20.800</u>.
