Please check the explanation.
Step-by-step explanation:
Given the sequence
A geometric sequence has a constant ratio 'r' and is defined by
Computing the ratios of all the adjacent terms
The ratio of all the adjacent terms is the same and equal to
Thus, the given sequence is a geometric sequence.
As the first element of the sequence is
Therefore, the nth term is calculated as
Put n = 5 to find the next term
now, Put n = 6 to find the 6th term
Thus, the next two terms of the sequence 40, 10, 5/2, 5/8... is:
<h3>Answer: Choice B</h3>
No, this is not a plausible value for the population mean, because 5 is not within the 95% confidence interval.
====================================================
Explanation:
The greek letter mu is the population mean. It has the symbol which looks like the letter 'u' but with a tail at the front or left side.
The question is asking if mu = 5 is plausible if the researcher found the 95% confidence interval to be 5.2 < mu < 7.8
We see that 5 is <u>not</u> in that interval. It's a bit to the left of 5.2
Since mu = 5 is not in the interval, it's not a plausible value for the population mean.
Have we ruled it out with 100% confidence? No. Such a thing is not possible. There's always room for (slight) error. The researcher would need to do a census to be fully confident; however, such practices are very time consuming and expensive. This is the main reason why statistics is important to try to estimate the population with a sample.
