Answer 2

Answer:

B. Mean: 339.20 (Median: 318) (Mode: 445.20) (Range: 243.80)

Step-by-step explanation:

A store sells models of cameras for $190.00, $420.00, $270.00, $300.00, and $420.00.

As a 6% tax will be levied on this as sales tax, the new prices will be, $201.40, $445.20, $286.20, $318, $445.20

Arranging them in ascending order,

201.40, 286.20, 318, 445.20, 445.20

Mean of the sample will be,

$\overline{x}=\dfrac{201.40+286.20+318+445.20+445.20}{5}=\dfrac{1696}{5}=339.20$

Median is the middle value of the sample. So median will be 318.

The highest number of occurrences is the mode of the set. So mode is 445.20
