uppose a company that manufacturers game consoles (such as the X-Box, Playstation) needs to be “within industry standards,” which requires them to produce console that weighs an average of µ0 = 9.00 lbs. Construct a 90% confidence interval using a sample of 64 consoles from their production process, and that sample generates a sample mean of 8.00 lbs. Assume that the population standard deviation is known to be 4 lbs. Choose the most correct answer below regarding this problem. Some images are presented below as part of the question. Hint: use the z distribution to help. Also, check whether the interval you construct contains the hypothesized value of 9 lbs. a) a. figure 3 is the correct image for this confidence interval ; the interval is [5.86, 10.34] ; they are within industry standards b) b. figure 1 is the correct image for this confidence interval ; the interval is [7.18, 8.82]; they are within industry standards c) c. figure 4 is the correct image for this confidence interval ; the interval is [5.86, 10.34] ; they are within industry standards d) d. figure 2 is the correct image for this confidence interval ; the interval is [7.18, 8.82]; they are within industry standards e) e. figure 2 is the correct image for this confidence interval ; the interval is [7.18, 8.82]; they are not within industry standards
