Find the mean and standard deviation () for the following data set: 68.36, 15.31, 77.42, 84.00, 76.59,

Find the mean and standard deviation (σ) for the following data set:

68.36, 15.31, 77.42, 84.00, 76.59, 68.43, 72.41, 83.05, 91.07, 80.62, 77.83

Transform each raw score in the preceding data set into a z score, a T score, and an SAT score. The remaining exercises are based on SAT scores, with the assumption that they follow the normal distribution with μ = 500 and σ = 100.
