D. Surprisingly, a study found that children under stress reported toms of depression and anxiety but scored higher on a Lie Scale (a measure of tendency to give socially desirable responses). The population mean for the Lie Scale for nonstressed children is 3.8. A sample of 40 children under stress had a Lie Scale sample mean of 4.4, with a standard deviation of 2.5. Test the hypothesis that children under stress are more likely to give socially desirable answers. Write a complete conclusion in the context of the problem. Syt
