Answer:
a. Z-test of a population mean.
Step-by-step explanation:
The current owner claims that over the past 5 years, the average daily revenue was $675 with a standard deviation of $75.
This means that we have a large sample, which means that we can consider this to be the standard deviation for the population, which eliminates the t-test, leaving options a and c.
Population mean or proportion?
Mean, as a proportion is a value between 0 and 1, while average revenue may have lots of possible values. So the answer is given by option A.
Answer:
Initial: 25 40 60
Year 10: 25.70 40.50 60.25
Year 20: 27.45 42.70 64.50
Step-by-step explanation:
Answer:
x ≈ 30.7
Step-by-step explanation:
Reference angle = 61°
Opposite side length = x
Adjacent side length = 17
Applying the trigonometric function TOA, we have:
Tan 61 = opp/adj
Tan 61 = x/17
17 × Tan 61 = x
x ≈ 30.7
