A survey of 25 randomly selected customers found the ages shown (in years). The mean is 32.92 years and the standard deviation is 10.19 years. a) What is the standard error of the mean? b) How would the standard error change if the sample size had been 400 instead of 25? (Assume that the sample standard deviation didn't change.) 22 21 35 23 330 35 26 44 44 14 48 25 27 12 43 48 38 46 36 35 38 38 32 23 37 a) The standard error of the mean is. (Round to two decimal places as needed.) b) How would the standard error change if the sample size was 400 instead of 25 with the same sample standard deviation? Select the correct choice below and fill in any answer boxes within your choice. O A. The standard error would increase. The new standard error would be times the old. O B. The standard error would decrease. The new standard error would be the old standard error divided by OC. The standard error would not change.
