(b)

To determine

Reason behind the misleading of histogram.

Answer to Problem 11PPS

The graph is misleading as it is not starting from zero.

Explanation of Solution

Solution:

As the interval of graph is no start from zero so we can`t know about the correct information and there interval are not in uniform interval.

Conclusion:

The graph is misleading as it is not starting from zero.

(c)

To determine

Correction of misleading data.

Answer to Problem 11PPS

For correction the graph should start from zero and have uniform interval.

Explanation of Solution

Solution:

For correcting the histogram the interval should be in a uniform interval of 29 and start from zero i.e.0-29,30-59,60-89…,etc.

  

Conclusion:

For correction the graph should start from zero and have uniform interval.
