Question 1.If there are 50 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) 2.If there are 39 observations then how many degrees of freedom are there for the t distribution (for a sample mean) 3.If there are 34 observations then how many degrees of freedom are there for the t distribution (for a sample mean) 4.If the sample size is 53 and the population standard deviation is 13.06 then the standard error is ? (Answer to two decimal places)
