An athletics coordinator collected the 1-meter sprint times for 15-year old students at St lg natius's College. The sprint time assumes to follow a normal distribution with a mean of pr: 14.9? seconds and a variance of 02: [1411195 secondsz. Draw diagrams to help you solve the following problems 1. [1 mark] For a group of 41 fteen-year students randomly selected at St lgnatius's College, how many of them will have a \"MD-meter sprint time of 13.3 seconds or less? {integer} 2. [2 mark] How fast does a 15-year old student at St lgnatius's College have to mn to be the fastest 25% of WEE-meter sprinters? {3d p] [Hint: Draw a diagram to help check whether your answer makes sense or not] 3. [2 mark] The sprint time for a randomly selected 15-year student at St lgnatius's College ranges between \"1.051 standard deviations below the mean of a standard normal distribution and 0.9?3 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? {3dp} (Hint: Draw a standard normal diagram and clearly label the information onto the graph. Be careful with the sign.]
