Given that the average finishing time at the 2017 Australian inline marathon was approximately 2 hours and 24 minutes. The standard deviation was approximately 32.5 minutes. Assume the finishing times are normally distributed. If a skater wants to finish in the top 10% of the fastest times, what time does the skater need? Fastest 10% are those with LOW times. 102.4 minutes 190.3 minutes 176.5 minutes 210.4 minutes What is the probability of finishing in less than 1 hour and...
