Step-by-step explanation:
Consider the provided information.
The weekly sulfur dioxide emissions follow a normal distribution with a mean of 1000 ppm (parts per million) and a standard deviation of 25.
Thus, μ=1000 and σ = 25
The CEO wants to know if the mean level of emissions is different from 1000.
Therefore the null and alternative hypothesis is:
and
The sample size is n = 50 and ppm.
Now calculate the test statistic by using the formula:
Substitute the respective values in the above formula.
Hence, the correct option is b) 1.70
Answer:
Number of carnations = 6
Step-by-step explanation:
Let the number of carnations school band buys from florist be x.
Cost of each carnation = $0.50
Total cost for x number of carnations = $0.50x
Also , delivery cost = $15
So, total cost on buying x number of carnations from florist = 0.50x + 15
Now,
School band sells carnations at a price of $3 each.
Total revenue they get get after selling x number of carnations = $3x
We need to find that , when will the cost of the carnations be equal to the revenue from selling them.
i.e 3x = 0.50x + 15
or 3x - 0.50x = 15
or 2.50x = 15
or x =
or x = 6
so on selling 6 carnations cost of carnation reach to the point where it is equal to revenue
