study was conducted to explore whether perception of money by preschool age children is influenced by their family wealth. This was investigated by testing how the children would recall the size of a coin, with the assumption that the size recalled related to the value placed on the coin. Test the claim that the proportion of children from the low income group that drew the nickel too large is greater than the proportion of the high income group that drew the nickel too large. Test at the 0.01 significance level. Of the 40 children in the low income group, 22 drew the nickel too large, and 11 of 35 did in the high income group. a) If we use L to denote the low income group and H to denote the high income group, identify the correct alternative hypothesis.
