Question at position 3  What is the output of the following code? x = c(0, 1, 1, 2, 3, 5, 8, 13, 21, 34)mean(x) 8.89.510.515.0

To solve this, we first identify the data set given: x = c(0, 1, 1, 2, 3, 5, 8, 13, 21, 34). The task is to compute the mean, which is the sum of all elements divided by the number of elements.

Next, we add the numbers step by step: 0 + 1 = 1, +1 = 2, +2 = 4, +3 = 7, +5 = 12, +8 = 20, +13 = 33, +21 = 54, +34 = 88. The total sum is 88.

There are 10 elements in the vector, so the mean is 88 divided by 10, which equals 8.8.

Option by option analysis:
- 8.8: This value matches the computed mean exactly, since 88/10 = 8.8. It reflects the correct average of the given numbers.
- 9.5: This would imply a total sum of 95 for ten numbers, which is not the case here; the actual sum is 88.
- 10.5: This would correspond to a total sum of 105, which again does not align with the real sum of the elements.
- 15.0: This would require a much larger total sum (150) for ten numbers, far from the computed total of 88.

In summary, the mean of the provided vector is 8.8, and the other options fail to match the correct total and division-based calculation.
