Question

Heights of adult males are known to have a normal distribution. A researcher claims to have randomly selected adult males and measured their heights with the resulting relative frequency distribution as shown here. Identify two major flaws with these results. Height​ (cm) Relative Frequency   130 dash –144 22 22​% 145 dash –159 25 25​% 160 dash –174 21 21​% 175 dash –189 26 26​% 190 dash –204 28 28​%

Answer 1

Explanation:

Answer 2

From the table the major flaws that can be identified are:

1. The sum of the relative frequencies of the dat set is greater than 100% which is not possible.
For any dataset, the sum of the relative freduency must be 100%

2.) the distribution of the data is not symmetric.
