$277.36
$305.37
$356.27
$437.18

Explanation:

Step1: Calculate the sum of deposits

$$1227.09 + 29.78+437.18 + 277.36+33.98+15.21+117.00$$
$$=(1227.09+29.78)+437.18 + 277.36+33.98+15.21+117.00$$
$$=1256.87+437.18 + 277.36+33.98+15.21+117.00$$
$$=(1256.87+437.18)+ 277.36+33.98+15.21+117.00$$
$$=1694.05+ 277.36+33.98+15.21+117.00$$
$$=(1694.05+277.36)+33.98+15.21+117.00$$
$$=1971.41+33.98+15.21+117.00$$
$$=(1971.41+33.98)+15.21+117.00$$
$$=2005.39+15.21+117.00$$
$$=(2005.39+15.21)+117.00$$
$$=2020.6+117.00$$
$$=2137.6$$

Step2: Calculate the number of deposits

There are 7 deposits.

Step3: Calculate the mean

The formula for the mean $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $\sum_{i=1}^{n}x_{i}$ is the sum of the data and $n$ is the number of data points.
So, $\bar{x}=\frac{2137.6}{7}=305.3714\approx305.37$

Answer:

$305.37$
