Step 1:: To find the mean of a data set, sum up all the numbers and then divide by the count of numbers.
The sum of the data set is $$35 + 43 + 81 + 30 + 41 + 95 + 103 + 43 + 96 = 601$$.
Step 2:: The count of numbers in the data set is 9.
Step 3:: Compute the mean by dividing the sum by the count.
Mean $$= \frac{\text{Sum of data set}}{\text{Count of numbers}} = \frac{601}{9} \approx 66.78$$.
Final Answer
The mean of this data set is approximately 66.78.
