Answer:
3.45
Step-by-step explanation:
The sample mean of the random sample is 50
The margin of error (E) is the amount of error allowed in the random sample.
The confidence interval (CI) is given by:
CI = μ ± E = (μ - E, μ + E)
Given a confidence interval of (38.02, 61.98), hence:
μ - E = 38.02 (1)
μ + E = 61.98 (2)
Hence solving equations 1 and 2 simultaneously gives:
μ = 50, E = 11.98
Hence the sample mean of the random sample is 50

What's this for?
And is that X2 supposed to be a squared?
It would be 250 cu. ft.
Say the larger box measures 10x10x20 which would give you a volume of 2,000 cu. ft. The smaller box then would measure half of those lengths or 5x5x10 which would be 250 cu. ft.
