Use the table to answer the following question. Grade 10-12 Height Range 55-59 60-64 65-69 70-74 Frequency 4 9 8 4 A statistician collects the following height data in inches for a school district. The statistician says that it is a normal distribution. How did they draw this conclusion? (1 point) Responses The frequencies for the first and last height range are the same. The frequencies for the first and last height range are the same. When graphed, the data creates a bell curve. When graphed, the data creates a bell curve. The frequencies for each height range are different. The frequencies for each height range are different. When graphed, the data creates a straight line.
1 answer
The correct response is: When graphed, the data creates a bell curve.
This is because a normal distribution is characterized by its bell-shaped curve when the frequencies of the data are plotted. The given frequencies (4, 9, 8, 4) suggest that the data has a peak around the middle range, which is indicative of a normal distribution.
