Answer correctly?  That makes it harder.

I'm going to sort the data and drop the negative signs; we just have to remember to put them back as needed later.

9 12 14 18 39 43 49 49

We have n=8 data points.

The mode is the most frequent data value; here it's 49, which occurs twice, really -49.

The range is max - min, so 49 - 9 = 40.  That one doesn't get a minus sign; range is always positive.

The sum of the points is 9+12+14+18+39+43+49+49=233

The mean is sum/n = 233/8 = 29.125, really -29.125

That's enough to answer the question, but for completeness let's get the median, which is the middle value.  When we have an even number of values, 8 here, it's the average of the two middle values, the fourth and fifth, here.

median is (18 + 39)/2 = 28.5, really -28.5

mean -29.1, median -28.5, mode -49, range 40; last choice

what is the question?
