Researchers were interested in play types. Children in 3 age groups were compared. The researchers measured the number of minutes out of a 30 minute time sample that the children engaged in social play (associative or cooperative play). Interpret the Excel output obtained at the
5% significance level (a = 0.05). What conclusion can the researchers draw? Interpret the Post Hoc tests using the Bonferroni procedure. Write the step 5 answer (formal APA format notation and conclusions; round your answer to 2 decimal places).
