An athletics coordinator collected the 100-meter sprint times for 15-year old students at Riverside Girls High School. The sprint time assumes to follow a normal distribution with a mean of p: 14.25 seconds and a variance of 0-2: 0.36 secondsz. Draw diagramstohelpyou solve the following problems 1. (1 mark) For a group of 39 fifteenyear students randomly selected at Riverside Girls High School, how many of them will have a loo-meter sprint time of 15.08 seconds or less? . (integer) 2. (2 mark) How fast does a 15-year old student at Riverside Girls High School have to run to be the fastest 33% of mil-meter sprinters? (ado) (Hint: Draw a diagram to help check whether your answer makes sense or not) 3. (2 mark) The sprint time for a randome selected 15-year student at Riverside Girls High School ranges between 1.858 standard deviations below the mean of a standard normal distn'bution and 0.049 standard deviations above the mean of a standard normal distribution. What is the probability of another randomly selected 15-year student having the same Sprint time range? [Sop] (Hint: Draw a standard normal diagram and cleariy label the information onto the graph. Be careful with the sign.)
