Question

Use the following scenario to complete the question 1 through 3. page 233.Q7.26) An orange juice producer buys oranges from a large orange grove that has one variety of orange. The amount of juice squeezed from one of these oranges is approximately normally distributed, with a mean of 4.70 ounces and a standard deviation of 0.4 ounce. 1. What is the probability having the amount of juice squeezed from one orange will be at least 4.60 ounces? (in dismal format) 2. Suppose that you select a sample of 25 oranges, what is the probability that the sample mean amount of juice will be at least 4.6 ounces? (in dismal format) 3.90% of the sample mean amount ofJuice are between what two values, symmetrically distributed around the mean? (keep 2 digits after the dismal place, e.g. 2.22) 4. Construct a 90% confidence interval estimate for the population mean given: X-70, o-15, and n-13. (keep 2 digits after the dismal place, e.g. 2.22) 5. Construct a 94% confidence interval estimate for the population mean given: X-300,-55, and n-250. (keep 2 digits after the dismal place, e.g. 2.22)
