The correct answer is C.
The mean is computed by adding all the elements that conform the dataset and by subsequently dividing the result obtained between the size of the dataset, which in this case is 7, that is the number of elements that constitute the dataset.
mean= (37 + 29 + 36 + 39 + 43 + 32 + 29) / 7= 35
The mode of a dataset is the value that is present more times. Therefore, in the dataset presented the mode is 29, as this value appears twice while the other values appear just once.
