Response times of 4 jobs are 5, 1, 3 and 3. How many jobs have their response time greater than the average response time?

To solve this question, the user needs to know the formula for calculating the average and be able to compare each job's response time to the average response time.

The formula for calculating the average is:

average = (sum of all values) / (number of values)

In this case, the sum of all values is:

5 + 1 + 3 + 3 = 12

The number of values is:

4

So the average response time is:

average = 12 / 4 = 3

Now, we need to compare each job's response time to the average response time (which is 3).

The first job has a response time of 5, which is greater than the average response time of 3.

The second job has a response time of 1, which is less than the average response time of 3.

The third job has a response time of 3, which is equal to the average response time of 3.

The fourth job has a response time of 3, which is equal to the average response time of 3.

So, only one job has a response time greater than the average response time.

Option A is the correct answer.

The Answer is: A
