Question

determine the range and standard deviation of the prices of digital cameras shown below.

\\$158, \\$94, \\$176, \\$180, \\$95, \\$128, \\$228, \\$277

the range of the prices is \\$\box.
(simplify your answer.)

the standard deviation of the prices is \\$\box.
(round the final answer to the nearest cent as needed. round all intermediate values to the nearest cent as needed.)

Answer:

Determine the range and standard deviation of the prices of digital cameras shown below.

$158, $94, $176, $180, $95, $128, $228, $277

The range of the prices is $<blank>183</blank>.
(Simplify your answer.)

The standard deviation of the prices is $<blank>63.46</blank>.
(Round the final answer to the nearest cent as needed. Round all intermediate values to the nearest cent as needed.)
