Collective data from the entire class = random numbers(from 53 to 64) for 25 students

Statistics, Lab #5 Name: , Normal Distribution Lgb Measure the circumference of your head in em. as if you are measuring to buy a perfect tting hat. . This was done on your initial assignment. C erS . - Collective data from the entire class. - - , \"MW. Tlmu "MEANWHILE AHEAI.) iN Tl Il'.' "(JAE)" 2. Compute J? = , and SK = 3. Construct a histogram with the scaling: x-min: f - 3 0 Sn, x-max: f + 3 - Sx and xsel: S; ' 4. Draw a smooth curve through the bars of the histogram, and comment on the shape of the above distribution. 6. Create the interval of one standard deviation about the mean, that is: :E 5,, f + SJ! 7. Find out what percent of the data falls within the interval in part 6. (That is number of data values in the above interval divided by total number of data values in your sample.) Give. a fmetteu a: watt a: a decimal or percent value. 8. Create the interval of two standard deviation about the mean. 2? 2.5:, J? + 2-8; 9. Compute the percent of the data that falls in the interval om part 8. Give. a fracblon as well. u a decimal. or Percent value. 1.0. Find out exactly what percent of the data supposed to fall within one standard :u . of the mean, assuming a normal distribution for this variable
