She takes a random sample of 30 apples and nds the average diameter to be E = 2.93 inches. Suppose the known population standard deviation ofthe diameter of honeycrisp apples is 0' : 0.9 inches. Use this information to answer the questions below. a. Compute an 87% condence interval for u, the average diameter of organic honeycrisp apples. Round your answers to at least five decimals if necessary Lower (smaller) bound: E inches Upper (larger) bound: E inches b. Interpret the interval calculated in part a. We are E condent that the average diameter of 7 v is ? v the upper and lower bounds of the interval in part a.
