Answer:
a)
b)
Step-by-step explanation:
Given that:
population mean = 30,000
sample size n = 800
population proportion p = 0.6
a)
The mean of the the sampling distribution is equal to the population proportion.
b)
The standard deviation of the sampling distribution can be estimated by using the formula:
Answer: First option is correct.
Explanation:
Since we have given that
Radius = 11 inches
Height = 14 inches
Now, according to question, we have mentioned that all the dimensions of the cylinder is to be quadrupled i.e. four times.
Then,
Radius is given by
Height is given by
As we know the formula for " Volume of cylinder ":
Hence, our volume of new similar cylinder is 340426.24 cubic in.
Therefore, First option is correct.
