Indicate whether each statement regarding the use of the Student's t distribution is true or false: True False a) For sample sizes greater than 40, the results of hypothesis tests and confidence intervals using the t distribution are highly sensitive to non-normality of the sample data b) The use of the t distribution assumes that the population from which the sample is drawn is normally distributed c) For small sample sizes, the t distribution should not be used for data that is highly skewed and/or contains extreme outliers d) Since the t distribution procedure is robust, it can be used even for small sample with strong skewness and extreme outliers
