Answer:
32 days must be sampled to test the proposed hypothesis.
Step-by-step explanation:
Consider the provided information.
The average number of person-hours per day spent on these task was 
.
The actual value of μ is 12 hours or less i.e μ=12
She wants a test having α=0.05
The probability of a type II error of at most β=0.10 and σ=7.64.
δ = μ-μ0
= 12-16
= -4
Now use the formula for calculating the sample size:
Substitute the respective values.
Hence, 32 days must be sampled to test the proposed hypothesis.

Answer:
70 m²
Step-by-step explanation:
Red sides:
2 x ( 5 x 5 ) = 2 x 25 = 50
Blue side :
2 x ( 1 x 5) = 2 x 5 = 10
Green :
2 x ( 1 x 5 ) = 2 x 5 = 10
Total surface area:
50 + 10 + 10 = 70
Units : m²
Surface Area = 70 m²
