Question

The following data set represents the lifetime of a sample of AA batteries(measured in hours). Construct a frequency distribution for the data. Also report the relative frequencies for each class of your distribution. 381, 225, 482, 580, 506, 110, 403, 180, 406 499, 264, 483, 380, 531, 430, 419, 564, 401 220, 698, 284, 340, 329, 341, 400, 387, 300 462, 280, 475, 427, 420, 509, 416, 622, 554 540, 336, 106, 418 The following data set represents the lifetime of a sample of AA batteries(measured in hours).

Explanation / Answer

If interval is 100-200, the data value 200 is included in next class.

Following table shows the frequency distribution and relative frequencies :

Interval frequency (f) Relative Frequency (f/N) 100-200 3 0.075 200-300 5 0.125 300-400 8 0.2 400-500 15 0.375 500-600 7 0.175 600-700 2 0.05 Total N=40
