It is important to the Wrigley Company to have a certain number of certain flavours in each skittles bag.

Recently, there has been complaints that the number of green shells is much lower than any other colour on average. A data analyst working for the company decides to test this. She selects 86 packs of skittles and counts the number of green skittles in each. She finds that there are a mean number of 7 green skittles in each pack, with a standard deviation of 2.7. What is the standard deviation of the sampling distribution for the sample mean?

Note:

1- Round any intermediate numbers to 4 decimal places.

2- Round your final answer to 3 decimal places. Enter your final answer with 3 decimal places.
