1. While reading a published research report, the following is reported: "When we examined the perceptual skills data, the mean of 12.00 from the sample of 50 adolescents differed significantly from the population mean of 15.00 for adults, [t(49) = 4.8, p<.05]" Find the given N value. 2. What hypothesis testing was performed? I test Z test 3. What aa level was used for the conclusion? 4. What aa level was used for the conclusion? 0.10 0.01 0.05 5. Find TobtTobt from the research conclusion above.(computation is not necessary) 6. Find Tcrit using a T table. 7.What is the result in terms of accepting or rejecting the null hypothesis at \alphaa=0.05? 1/3 8. Can we reject the null hypothesis at \alphaaa of 0.01? Support your conclusion using Tobt and Tcrit 9. Does the sample mean of adolescents differ significantly from the population mean? (Hint: based on your answers on #12) 10. Does the sample mean of adolescents differ significantly from the population mean? (Hint: based on your answers on #12) Yes, because Ho is rejected at 0.01 level of confidence. Yes, because H1 is rejected at 0.01 level of confidence. No, because H1 is rejected at 0.01 level of confidence. No, because Ho is rejected at 0.01 level of confidence.
