Answer 1

Answer:

The correct answer is 2.94 in.

Step-by-step explanation:

The monthly precipitation for August in 20 different U.S. cities are observed in inches.

The data is given by: 3.5, 1.6, 2.4, 3.7, 4.1, 3.9, 1.0, 3.6, 4.2, 3.4, 3.7, 2.2, 1.5, 4.2, 3.4, 2.7, 0.4, 3.7, 2.0 and 3.6.

We intend to find the mean of the given data.

Therefore mean of the precipitation is ∑data ÷ 20 = $\frac{58.8}{20}$ = 2.94 inches.

Thus the mean of the data is 2.94 inches.
