It is suggested that you draw a normal curve, label the z-values for 1, 2, and 3 standard deviations from the mean, and write in the probabilities between each standard deviation before attempting to answer the questions. The average life-span of a True Test auto battery is 42 months with a standard deviation of 4 months. Assume a normal distribution. 1. We can expect 95% of the batteries to last between and % of the batteries to last less than 30 months. months. 2. We can expect 3. We can expect % of the batteries to last longer than 42 months. 4. We can expect % of the batteries to last between 30 and 38 months. 5. We can expect % of the batteries to last between 42 and 50 months.
