Construct the boxplot and describe the distribution shape The weights (in pounds) o30 newborn babies are listed below. Construct a boxplot (to scale) for the data and describe the distribution shape. 5.5 5.7 5.8 5.9 6.1 6.1 6.3 6.4 6.5 6.6 6.7 6.7 6.7 6.9 7.0 7.0 7.0 7.1 7.2 7.2 7.4 7.5 7.7 7.7 7.8 8.0 8.1 8.1 8.3 8.7 5.5 7.0 7.7 8.7 6.4 The data is highly symmetrical. Iis a uniform distribution. 5.5 6.4 7.0 7.7 8.0 The data is slightly left skewed. 5.5 6.3 7.0 7.7 8.7 The data is slightly right skewed.

Explanation / Answer

here miimum =5.5

maximum =8.7

Q1 =(n+1)/4 th value =(30+1)/4 th value =7.75 th value =6.3+0.75*(6.4-6.3)=6.375

median =(n+1)/2 th value =(30+1)/2 th value =15.5 th value =(7+7)/2 =7

Q3 =3*(n+1)/4 th value =3*(30+1)/4 th value =23.25 th value =7.7+0.25*(7.7-7.7)=7.7

therefore last option is correct.
