A study was conducted to assess the effects that occur whenchildren are exposed to cocaine before birth. Children were testedat age 4 for object assembly​ skill, which was described as​ \"atask requiring​ visual-spatial skills related to mathematical​competence.\" The 196 children born to cocaine users had a mean of7.4 and a standard deviation of 2.9. The 183 children not exposedto cocaine had a mean score of 8.3 with a standard deviation of3.1. Assume that the two samples are independent simple randomsamples selected from normally distributed​ populations, and do notassume that the population standard deviations are equal. Letpopulation 1 be children born to cocaine users
Identify the null and alternative hypotheses
State the conclusion for the test.
