Ineed :

a store sells models of cameras for $190.00, $420.00, $270.00, $300.00, and $420.00. if the sales tax rate is 6%, what are the mean, median, mode, and range of the total cost of the cameras?

a) mean: 318 (median: 339.20) (mode: 445.20) (range: 21.20)

b) mean: 339.20 (median: 318) (mode: 445.20) (range: 243.80)

c) mean: 339.20 (median: 318) (mode: 445.20) (range: 21.20)

d) mean: 445.20 (median: 318) (mode: 339.20) (range: 243.80)

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,

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

sine
