The number of snow days in District 241 is 4 given that the mean of the data set is 5. This can be obtained by using formula for mean of a data and simplifying the obtained equation for the required value.
The formula of mean of a data is given by,
⇒ Mean = sum of all items/total number of items
Here in the question it is given that,
/school disctrict/district 201/district 211/district 221/district 231/district 241/
/no. of snow days/ 4 / 8 / 3 / 6 / ? /
We have to find the number of snow days in District 241.
Let the number of snow days in District 241 be x.
By using formula of mean of a data we can write that,
Mean = (4 + 8 + 3 + 6 + x)/5
5 = (21 + x)/5
25 = 21 + x
x = 4 snow days
Hence the number of snow days in District 241 is 4 given that the mean of the data set is 5.
