For this question, any non-integer answers should be entered as decimals, rounded to the hundredths place. consider this data set. the mean of the data set is , and the sample proportion of numbers less than the mean is %

Mean =22.1

The sample proportion of numbers less than the mean is = (7/15 ) *100 =46.67%

Explanation:

Mean of the data set can be calculated by adding all numbers and dividing it with total number sample data.

Adding all the numbers

25.5 + 26 +18.2 +15.3 + 28.5 + 27 + 20.7 +20.2 +26.1 +18.2 +21.4 +17.9 +24.3 +22.6+ 19.6 =331.5

    2. Dividing by total

331.5/15 =22.1

If there was no gravity then their would be no downword force on the football to have it return the the grownd, and if there was no friction (mainly air friction) then there would be no opposing force the stop the ball from moving through the air allowing the ball to travle ∞.

Ithink the answer would be a
