peds (small motorcycles with an engine capacity below 50 cm) are very popular in Europe because of their mobility, ease of operation, and low cost. Suppose the maximum speed of a moped is normally distributed with mean value .8 km/h and standard deviation 1.75 km/h. Consider randomly selecting a single such moped. A USE SALT ) What is the probability that maximum speed at most 50 km/h? (Round your answer to four decimal places.) 0.0884 ) What is the probability that maximum speed is at least 48 km/h? (Round your answer to four decimal places.) 0.254G :) What is the probability that maximum speed differs from the mean value by at most 1.5 standard deviations? (Round your answer to four decimal places.) 0.4332 u may need to use the appropriate table in the Appendix of Tables to answer this question.
