A survey of 25 randomly selected customers found that their average age was 31.84 years with a standard deviation of 9.84 years. What is the standard error of the mean? How would the standard error have changed if the sample size had been 100 instead of 25 (assuming that the mean and standard deviations were the same)? How many degrees of freedom would the t-statistic have for this set of data? What would the critical value t* be for a...
