HELP Sam measures the height of 7 different scoops of ice cream. The mean of the heights was 3.8 cm. Which of the following best
OLga [1]

Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm. If all the scoops are evenly distributed, they would all be 3.8 cm tall.

<h3>How to find the mean value of a data set?</h3>

The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.

If the data set consists of values

x_1, x_2, ..., x_n

, then we get the mean value as:

\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}

Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm.

\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}

mean=\dfrac{(a+b+c+d+e+f+g)}{7}

Therefore, If all the scoops are evenly distributed, they would all be 3.8 cm tall.
