1. Researchers investigating characteristics of gifted children collected data from schools in a large city on a random sample of thirty-six children who were identified as gifted children soon after they reached the age of four. The following histogram shows the distribution of the ages (in months) at which these children first counted to 10 successfully. Also provided are some sample statistics. 6- 3- 0 20 25 30 35 40 Age child first counted to 10 (in months) (a) Are conditions for inference satisfied? n 36 min 21 mean 30.69 sd 4.31 max 39

'Researchers investigating characteristics of gifted children collected data from schools in a large city on a random sample of thirty-six children who were identified as gifted children soon after they reached the age f four The following histogram shows the distribution of the ages (in months) at which these children first counted to 10 successfully. Also provided are some sample statistics_ Suppose you read online that children first count to 10 successfully when they are 32 months old, on average You perform a hypothesis test evaluating whether the average age at which gifted children first count to 10 is different than the general average of 32 months What is the p-value of the hypothesis test? Choose the closest answer. 36 min 21 mean 30.69 sd 4.31 max 39 20 25 30 35 40 Age when the child first counted to 10 successfully (in months) 0.7183 0.9656 0.0688 0.0344 0.9312'
