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.
Answer:
Sin 29° 32' = Cos 60° 28'
Step-by-step explanation:
Here in this problem, we have to write Sin 29° 32' in terms of its co-function.
We know that co-function of Sin Ф = Cos ( 90° - Ф ).
Therefore, we have to find a complementary angle of 29° 32'.
So, ( 90° - 29° 32' ) = 60° 28'
Therefore, Sin 29° 32' = Cos 60° 28' ( Answer )
