Step-by-step explanation:
Price for each camera = 14
Number of camera = 2dozen = 12 x 2 = 24
Total cp = 24 x 14 = 336
~~~~~~~~~~~~~~
Price for each camera= 10.99
Number of cams = 24
Total sp = 10.99 x 24 = 263.76
Loss = 336 - 263.76 = 72.24
Given:
μ = $3120, population mean
σ = $677, population standard deviation.
The population is normally distributed.
n = 20, sample size.
At the 95% confidence level, the confidence interval is

1.96(σ/√n) = 1.96(677/√20) = 296.71
Th confidence interval for the mean is
($2823.29, $3416.71)
Answer: ($2823.29, $3416.71)
