Answer: Mean = 284
Step-by-step explanation:
Data:
125, 126, 127, 127, 137
201, 202, 207, 211, 215, 218, 224, 237, 261
301, 308, 310, 315, 330, 330, 360, 380, 393, 394
401, 401, 410, 421, 422, 424
Class Frequency Table:

Mean:
The sum of the numbers divided by the quantity of numbers:
8518/30 = 283.933
Cumulative Frequency Histogram:
Create the graph based on the Interval and Cumulative Frequency of the class frequency table above. (see image)
