E

(23 + 19 + 15 + 30 + 27 + 25)/6 = 23.2

To calculate the mean arithmetic annual number of women receiving a doctorate degree in computer and information sciences, we need to find the average of the number of women for each of the six years.

Given the following data: Year 1: 23 women Year 2: 19 women Year 3: 15 women Year 4: 30 women Year 5: 27 women Year 6: 25 women

To find the mean, we add up the number of women for each year and divide by the total number of years (which is 6 in this case).

Mean = (23 + 19 + 15 + 30 + 27 + 25) / 6 Mean = 139 / 6 Mean = 23.17 (rounded to two decimal places)

Therefore, the mean arithmetic annual number of women receiving a doctorate degree in computer and information sciences is approximately 23.17.

Looking at the answer choices provided, we can see that the closest option to the calculated mean is option E: 23.2.
