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 o = 8; C = 95%; E = 3 O o = 3; C = 90%; E = 8 O o = 8; C = 90%; E = 3 O 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
