Question

the prices of four phones are $143, $172, $241, and $196. progress: 0/3 part 1 of 3 (a) find the mean of these prices. the mean price of the phones is $□.

Explanation:

Step1: Recall mean formula

The mean $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $x_{i}$ are the data - points and $n$ is the number of data - points. Here $n = 4$, $x_1=143$, $x_2 = 172$, $x_3=241$, $x_4 = 196$.

Step2: Calculate the sum of prices

$\sum_{i=1}^{4}x_{i}=143 + 172+241+196=752$.

Step3: Calculate the mean

$\bar{x}=\frac{752}{4}=188$.

Answer:

$188$
