E Question Help The data represents the body mass index (BMI) values for 20 females Construct a trequency distribution beginning 177 335 267 253 214 class limit of 15 0 and use a class width of 6 0 Does the frequency distribution appear to be roughly a 28 9 233 183 27.7 258 normal distribution? 24.4 32.7 37.7 29 2 34.6 Body Mass Index 15.0-209 21.0-26.9 27.0-32 9 Fr Body Mass Index 330-38 9 39.0-44.9 Does the frequency distribution appear to be roughly a normal distrbution? Click to select your answer(s).Explanation / Answer
ans=
Class iinterval: 15.0 - 20.9 21.0 - 26.9 27.0 - 32.9 33.0 - 38.9 39.0 - 44.90
Frequency: 3 8 5 3 1
From the frequency table, it can be seen that the frequencies started low, increased to a point and then decrease. It can also be seen that the highest frequency of the data is not at the center of the distribution, so the distribution is not symetric.
Therefore, the frequency distribution does not appear to be roughly a normal distribution, because, "although the frequency start low, increase to some maximum, then decrease, the distribution is not symmetric."
