Determine if the following are true or false: [Choose ] As n increases the t-distribution approaches the standard normal distribution. As n increases, the tails in the t- distribution become "fatter". [Choose ] [Choose ] The shape of a t-distribution depends on its degrees of freedom. [Choose ] We will always use a student'st distribution when we are given raw data to analyze, regardless if we know the population standard deviation or not. t-distributions are similar in shape to the standard normal curve. [Choose] [Choose ] We use the Student's t-distribution when we estimate the mean of a population that is normally distributed, has an unknown standard deviation, and small n.
