Juice that is opened. It is known that the annual profits earned by health-drink franchises has a population standard deviation of $8,700
........
Answer:
z = 1.157
Step-by-step explanation:
Given
Annual profit as calculated = $90,300.
H0: μ = 89,000
Ha: μ > 89,000
σ = 8700
n = 60
Calculate the test statistic (z) that corresponds to the sample and hypotheses.
Test statistic (z) is calculated by
z = (x - μ)/(σ/√n)
Where x = 90,300
μ = 89,000
σ = 8700
n = 60
z = (90,300 - 89,000)/(8700/√60)
z = 1.157443298866584
z = 1.157 ----- Approximated
It is 30. The square root of 900 is 30.
Answer:
Sylvia needs to work at least 19 hours.
