Question
Answer all of them thanks (a-d)
Transcribed Image Text:2.Clean Water wants to estimate the mean number of gallons of alkaline water
orders they get each day. Suppose that they want a 95% confidence level that
the estimate is accurate within 3 gallons knowing that the standard deviation is
about 8 gallons. What should be the minimum sample size that they need in order
to make this estimate?
a. Based from the situation, what are the given values? *
o = 8; C = 95%;E = 3
O o = 3; C = 90%; E = 8
o = 8; C = 90%; E = 3
o = 3; C = 95%; E = 8
b. Based from the given data, what is the z critical value? *
1.654
1.960
2.575
1.965
c. Using the formula for estimating sample size (n), what is the computed
value in 2 decimal places? *
3 points
Your answer
Transcribed Image Text:c. Using the formula for estimating sample size (n), what is the computed
value in 2 decimal places? *
Your answer
Thus, the minimum sample size that they need in order to make the estimate is
(d.) alkaline water orders.
d. What is the minimum sample size as a whole number? *
