1. Well, you can use the distributive property, i.e., you can multiply the entire thing by an integer to get a multiple of the term. So:
2. The 18th customer will because 18 is a multiple of 6 as well as 9. You could also say 36th, 54th, or even further: just keep adding 18. Symbolic Representation:
∞
∑ (Something that says "this repeatedly adds up to 18")
n=1
3.
*Not sure about this one.

Answer:
(0.767,0.833)
Step-by-step explanation:
The 95% confidence interval for population proportion p can be computed as
The z-value associated with 95% confidence level is 1.96.
whereas p=x/n
We are given that x=440 and n=550.
p=440/550=0.8
Thus, the required confidence interval is
0.767<P<0.833 (rounded to 3 decimal places)
Hence, we are 95% confident that our true population proportion will lie in the interval (0.767,0.833)
