Not sure if I answered these correctly

The National Immunization Survey reported the immunization rate (the percentage of children aged 12 to 35 months who have received all their recommended shots) for each of a random sample of 37 communities throughout the United States. The data are summarized in the stemplot below.

Obtain the median immunization rate for this group of 37 communities.

47

Obtain the inter-quartile range of immunization rates.

IQR= 54-38

Use the quartile-based method to determine if the data set contains any outliers. If you detect any outliers, identify them.

54+1.5(16)= 78, 38-1.5(16), yes outliers are present, 14-22?
