A social psychologist records the age (in years) that a sample of eight participants first experienced peer pressure. The recorded ages for the participants are 14, 20, 17, 16, 12, 16, 15, and 16. Compute the SS, the variance, and the standard deviation for this sample using the definitional and computational formula. Please show step by step.

1) Calculate the variance and standard deviation for each sample. (4 points) Note: you can use the Definitional Formulas (Slides #10 and 12) to compute sa and s, or you can choose the Computational Formulas (Slide #13). Either way is fine because the computational formula is just another form of the definitional formula, as discussed in the video. 2) In relation to the size of the mean values from two samples, what do the different standard deviations between the two...
