Recall that the study (Keith, 2012) was carried out to examine the effects of a music intervention on the quantity of breast milk produced by mothers of preterm infants using a breast pump. MIlk_Quantity records the quantity of milk (in millilitres) produced by each mother on Day 3 of the study. A dot plot of this data is shown below. MIlk Quantity by Group Music No Music 40 80 100 120 MR Quantity Day 3 Milk Quantity by Group Note: For the purpose of this assessment the data above has been simulated based on the original results. Which one of the following statements about the data displayed in the plot above is false? O There are no outliers in this data. O To make a valid comparison of the average Milk Quantity between the two groups it would be important to use the mean rather than the median. The median Milk Quantity for the Music group is higher than the No Music group. O The standard deviations for both groups are similar. O The distribution of Milk Quantity for both groups is roughly symmetric. dnoup
