Extracted text: Use the table to answer each question. Note: Round z-scores to the nearest hundredth and then find the required A values using the table. The breaking point of a particular type of rope is normally distributed, with a mean of 320 pounds and a standard deviation of 24 pounds. What is the probability that a piece of this ro chosen at random will have the following breaking points? (Round your answers to three decimal places.) (a) less than 290 pounds (b) between 310 and 340 pounds
