1. If the sample size is 53 and the population standard deviation is 12.87 then the standard error is ? (Answer to two decimal places) 2. If there are 34 observations then how many degrees of freedom are there for the t distribution (for a sample mean)? 3. If there are 40 observations then how many degrees of freedom are there for the t distribution (for a sample mean)? 4. If there are 46 observations in a sample, how many degrees of freedom are there? (The context here is for finding a t value when constructing a confidence interval or testing a hypothesis for the pupoulation mean).
