Suppose that 95% of the bags of certain fertilizer mix weigh between 49 and 53 pounds. Averages of three succesive bags were plotted, and 47.5% of these were observed to lie between 51 and X pounds. Estimate the value of X. State assumptions you make and say whether these assumptions are likely to be true for this example.

- 3.6 Triathlon times, Part Il: The distribution for triathlon time varies depending on the population you are describing. The distribution for men ages 30 - 34 is N(u=4304, o=581). The distribution for women ages 25 - 29 is N(u=5225, o=848). Note, these distributions list the triathlon times in seconds. Use this information to compute each of the following. Report your answer to 2 decimal places. a) The cutoff time for the fastest 5% of athletes in the men's group, i.e. those who took the shortest 5% of time to finish. b) The cutoff time for the slowest 10% of athletes in the women's group.arrow_forward3.
