Question

Jon loves to go bird watching at a nearby animal sanctuary. Find the mean of the following numbers of birds he spotted at the sanctuary in the last few days: 14, 10, 17, 11, 9, 15, 6, 14.

a) 11.5
b) 13.5
c) 12.5
d) 10.5

Answer 1

The mean number of birds Jon spotted at the sanctuary is calculated by adding all the spotted birds together and dividing by the number of days, resulting in a mean of 12, which is not listed in the provided options.

Step-by-step explanation:

To find the mean of the numbers of birds Jon spotted at the sanctuary on different days, you simply need to add up all the numbers and then divide by the number of days.

The numbers are: 14, 10, 17, 11, 9, 15, 6, 14. First, we add them together:

14 + 10 + 17 + 11 + 9 + 15 + 6 + 14 = 96

Next, we divide the sum by the number of observations (which is 8 in this case):

96 ÷ 8 = 12.

Therefore, the mean number of birds Jon spotted is 12, which means the correct answer is not listed among the options provided. There might be an error in the question or the options given. Normally, such an error would need to be corrected to provide the right answer option.
