QUESTION 7 A study was conducted to assess the effects that occur when children are exposed to cocain before birth. Children were tested at age 4 for object assembly skill. The 190 children born to cocain users had a mean of 7.3 and standard deviation of 3.0. The 186 children not exposed to cocain had a mean score of 8.2 with a standard deviation of 3.0. Using d.f.= 140 in the t-table, find an interval for the p-value and make a decision at the 0.01 significance level. (Note that another question asks for the value of the test statistic.) (0.001, 0.010), reject the null hypothesis (0.0005, 0.005), fail to reject the null hypothesis. (0.001, 0.01), fail to reject the null hypothesis. (0.005, 0.005), reject the nul hypothesis
