A toy manufacturer claims that the median amount of time that their top selling toy captures children's attention is 30 minutes. To test this, a random sample of 19 children is selected and their attention span (in minutes) while playing with this toy is given below. 20.4, 26.1, 21.8, 25.4, 19.3, 34.9, 37.5, 26.3, 22.7, 24, 22.4, 38.9, 20.5, 30, 36.6, 23, 37, 24.7, 36.6 At the 0.02 level of significance, can we conclude (by using a sign test) that the median attention span for children playing with this toy differs from 30 minutes? Perform this hypothesis test by completing the table below. (If necessary, consult a table with critical values for the sign test.) Value of test statistic: Critical value: Decision: ▼(Choose one) Can we conclude that the median attention span for children playing with this toy differs from 30 minutes?
