Suppose 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 Ho = 8.50 lbs. Construct a 95% 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 8.50 lbs. 95 - 90 : 025 5 -1.96 & ods 0 1.%. -196 194 95 - ..025 1.645 0 1.645 -1.645 0 1.645
a) a. figure 3 is the correct image for this confidence interval; the interval is 17.02, 8.98]; they are within industry standards O b) b. figure 1 is the correct image for this confidence interval; the interval is (7.18, 8.82]; they are not within industry standards c) c. figure 4 is the correct image for this confidence interval; the interval is [7.02, 8.98]; they are within industry standards d) d. figure 1 is the correct image for this confidence interval; the interval is 17.02, 8.98]; they are within industry standards e) e figure 2 is the correct image for this confidence interval; the interval is [7.02,8.98]; they are not within industry standards
