STA 261 Lecture Notes - Lecture 2: Point Estimation, Sampling Distribution
Document Summary
Find the mean, up, and standarad error, op, based on the point estimate. Three ways to proceed: use normal calc on stat crunch. I am 90% confident that the true proportion of heads will be between . 273 and . 527. Z is the standard noral curve and is used when we are performing inference procedures for proportions. The t distribution is used when we are erforming inference procuedures for means. Many t crves, one for each degrees of freedom. Watch for outliers because mean and s are not resistant to outliers.
