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.
