Lemur [1.5K]

Answer:

$\bar x = 356.73$ ---Atlanta

$\bar x = 400.95$ --- Salt Lake City

Step-by-step explanation:

Given

The round trip flight data of Atlanta and Salt Lake City

Required

The mean price of both

Mean is calculated as:

$\bar x = \frac{\sum x}{n}$

For Atlanta

$\bar x = \frac{291.6 + 321.6 + 340.1 + 339.6 + 359.6 + 384.6 + 309.6 + 415.6 + 293.6 + 249.6 + 539.6 + 455.6 + 359.6 +333.9}{14}$

$\bar x = \frac{4994.2}{14}$

$\bar x = 356.73$

For Salt Lake City

$\bar x = \frac{570.1 + 354.6 + 465.6 + 219.6 + 311.6 + 297.6 + 471.6 + 618.4 + 513.6 + 523.2 + 381.6 + 159.6 + 267.6 + 458.6}{14}$

$\bar x = \frac{5613.3}{14}$

$\bar x = 400.95$
