Three hundred college students were randomly selected and the height was recorde

Question

Three hundred college students were randomly selected and the height was recorded for each. In order to check if the underlying distribution is normally distributed, a normal probability plot was constructed and is shown above. What conclusion is CORRECT concerning these data?

The heights are not normal because the plot does not conform well to a linear pattern, but has a curvilinear pattern instead. The heights are normal because the plot does not conform well to a linear pattern, but has a curvilinear pattern instead. The heights are normal because the pattern at normal score of 0 is approximately linear (vertical). The heights are not normal because the pattern at normal score of 0 is approximately linear (vertical). g 68- 66 64 62 LT Scatter plot of Heights vs NScores NScores

Explanation / Answer

The heights are not normal because the plot does not conform well to a linear pattern, but has a curvilinear pattern instead.

Here from the normal probability plot we can conclude that it is not properly linear and also from normal score 0 to 2 it is showing a curvilinear pattern. Hence the data is not coming from a normal distribution.
