When we draw a histogram and relative frequency histogram we can see the same histogram chart for the data set.
Except for the labeling of the vertical axis that is y-axis.
Therefore the correct option is D. True. A relative frequency histogram will have a different scale on the y-axis but the same shape as a regular histogram.

1. TRUE OR FALSE: If the Y-axis on a histogram or bar chart is changed from frequency to relative frequency, the shape of the graph will remain unchanged. 2. TRUE OR FALSE: The X-axis for a histogram displays numerical data. 3. TRUE OR FALSE: Bar charts and pie graphs are useful when presenting categorical data. 4. TRUE OR FALSE: The box in a box plot represents the standard deviation. 5. TRUE OR FALSE: The actual raw data can be reconstructed...

Use the given categorical data to construct the relative frequency distribution. Natural births randomly selected from four hospitals in a highly populated region occurred on the days of the week (in the order of Monday through Sunday) with the frequencies 53, 64, 68, 55, 59, 46, 55. Does it appear that such births occur on the days of the week with equal frequency? Construct the relative frequency distribution. Relative Frequen 13.25 % 16% 17 % 13.75 % 14.75 % 11.5...
