Find the mean of the following data: 89, 73, 84, 91, 87, 77, 94915958985

The data you provided seems to have an outlier (94915958985), which is significantly larger than the rest of the numbers. If this is not a mistake and you want to include it in the calculation, here's how you can calculate the mean:

1. Add up all the numbers: 89 + 73 + 84 + 91 + 87 + 77 + 94915958985 = 94915959186
2. Count the total number of numbers, which is 7 in this case.
3. Divide the total by the count: 94915959186 ÷ 7 = 13559437026.57

So, the mean of the data set is 13559437026.57. However, this result is heavily influenced by the outlier. If the outlier is a mistake and should be excluded, the mean would be significantly lower.
