- A coniidence interval estimate 1S desired for the gain in a circuit on a semiconductor device. Assume that the gain is normally distributed with o = 400. a) Construct ad 95% CI when n = 15 and x = 10,000 b) Was the interval accurate if the true mean of the gain is 9,700? c) Construct a 90% CI when n = 30 and x = 10,000.North End Coffee Roasters roast 300 bags of coffee per day in three shifts at an average rate of 62 bags/hour. During the first shift, 100 bags of coffee are roasted at 67 bags/hour and the next 100 bags are roasted at 80 bags/hour in the second shift. a) At what rate should North End roast their coffee in the third shift to meet the target average rate? (ans in exact fraction or rounded to at least 4 decimal place) Ans: ------- bags/hour b) After roasting each bag of coffee is sealed and labelled at the packaging stage at a rate of 91 bags/hour. What is the average rate of production for the entire process of roasting and packaging coffee beans at North End? (ans in exact fraction or rounded to at least 4 decimal place) Ans: ------- bags/hourThe geometric mean of two positive numbers a and b is the number sqrt(ab).
