1.) What is the best graph to use to determine the distribution of frequencies? Explain and draw the most suitable graph for the above data. Explain the
distribution that data follows. (25 points).
The world standard is to reach 30 seconds and the range for acceptance is [29.5;30.50].
2.) Calculate the Central Measures of Location and the Statistical Measures of Spread or Dispersion and determine if this training group is on par with world
standards. What do you conclude about the variability of the athlete results? (25 points)
3.) Calculate the 68%, 95.5% and 99.7% intervals of the above data. (25 points)
The trainer believes that there is a relationship between the time and the age of the athlete. He takes a random sample of twelve athletes. The results are
shown below:
Age 20 22 23 27 28 27 29 29 27 26 27 28
Time 29.7 29.6 29.9 30.1 30.0 30.0 30.1 30.0 30.2 30.1 30.2 30.3
4.) Calculate and interpret the correlation between time and age and explain what you think about trainer’s opinion. (15 points)
5.) Determine the best age to produce a time of 30 seconds on a 200m sprint. (10 points)
