The statistician says that it is a normal distribution. How did they draw this conclusion? (1 point) Responses When graphed, the data creates a bell curve. When graphed, the data creates a bell curve. When graphed, the data creates a straight line. When graphed, the data creates a straight line. The frequencies for each height range are different. The frequencies for each height range are different. The frequencies for the first and last height range are the same. The frequencies for the first and last height range are the same.

Answer 1

The correct response is: When graphed, the data creates a bell curve.

This indicates that the data follows a normal distribution, which is characterized by a symmetrical, bell-shaped curve. If the data is truly normally distributed, we expect higher frequencies in the middle height ranges and lower frequencies in the extreme height ranges, leading to the typical bell curve shape when plotted.
