Answer:
The 99% confidence interval for the population mean is 22.96 to 26.64
Step-by-step explanation:
Consider the provided information,
A sample of 49 customers. Assume a population standard deviation of $5. If the sample mean is $24.80,
The confidence interval if 99%.
Thus, 1-α=0.99
α=0.01
Now we need to determine 
Now by using z score table we find that 
The boundaries of the confidence interval are:
Hence, the 99% confidence interval for the population mean is 22.96 to 26.64
Answer:
(d) 1/√(s³)
Step-by-step explanation:
The expression can be simplified by making use of the rules of exponents.
<h3>Rules of exponents</h3>
The relevant rules are ...
![a^b\cdot a^c=a^{b+c}\\\\(a^b)^c=a^{bc}\\\\\left(\dfrac{a}{b}\right)^c=\dfrac{a^c}{b^c}\\\\a^{b/c}=\sqrt[c]{a^b}](https://tex.z-dn.net/?f=a%5Eb%5Ccdot%20a%5Ec%3Da%5E%7Bb%2Bc%7D%5C%5C%5C%5C%28a%5Eb%29%5Ec%3Da%5E%7Bbc%7D%5C%5C%5C%5C%5Cleft%28%5Cdfrac%7Ba%7D%7Bb%7D%5Cright%29%5Ec%3D%5Cdfrac%7Ba%5Ec%7D%7Bb%5Ec%7D%5C%5C%5C%5Ca%5E%7Bb%2Fc%7D%3D%5Csqrt%5Bc%5D%7Ba%5Eb%7D)
<h3>Application</h3>
The given expression can be simplified by applying these rules.

When working with percents change them to decimals so 70% is .70 because a percent is just the number over 100. If you try it yourself do 70 divided by 100 and see what you get. For this problem you then multiply that by sixty as the total number of people included, which gets you 42 votes.
Answer:
you have to do, x axis times y axis which should give you your answer.
