Suppose we calculate a 99% confidence interval and it is (-2, 5).  Describe the area associated with making a mistake    a) Bell shaped curve with -1.8 and 5.25 on either end.  5% chance of mistake for -1.8 or less and 5.25 or more (each).    b) Bell shaped curve with -2 and 5 on either end.  5% chance of mistake for -2 or less and 5 or more (each).    c) Bell shaped curve with -2 and 5 on either end.  0.5% chance of mistake for -2 or less and 5 or more (each).    d) Bell shaped curve with -1.8 and 5.25 on either end. 0.5% chance of mistake for -1.8 or less and 5.25 or more (each).

As the supervisor in charge of shipping and receiving, you need to determine the average outgoing quality in a plant where the known incoming lots from your assembly line have an average defective rate of 4.0%. Your plan is to sample 80 units of every 1,000 in a lo number of defects in a sample is not to exceed 3. Such a plan provides you with a probability of acceptance of each lot of 0.79 (79%). The average outgoing quality for the plant is =% (enter your response as a percentage rounded to two decimal places).
