1. A computer engineer tests the processing speed of a new network configuration and finds that a code can be processed with a mean speed of 7.1 seconds and standard deviation of 0.1 seconds. The data follows a normal distribution.   a. What range of processing speeds contains 95% of the data points?   b. The desired speed specification is 7.0 ± 0.2 seconds. What percent of processes would you expect to end up with a process speed that is too long? Draw a number line diagram comparing the design specification and expected variability.
