For this sort of problem, you need to be familiar with prefixes.
So:
megabyte = bytes
kilobyte = bytes
and a regular byte would just be
Now, you will need to do a conversion:
I'm going to explain this just in case, but we convert megabytes to regular bytes in the first half by using the information I gave you above. (In one megabyte, there are bytes!)
In the second fraction thought, remember one kilobyte is bytes. However, you usually only see one of each thing on the bottom of fractions, so you need to add a negative sign to the 3. (technically you could just do
, but I think it is more correct to do write it out how I did).
*** They do equal the same thing though! Do whichever way is easier for you!
Now, your answer should be:
kilobytes (1000 kilobytes)

Answer:
z-statistic
Step-by-step explanation:
We have to identify the correct test statistic to use with the given conditions.
- If the sample size is larger than 30, then the sample is considered to be large.
- We are given a sample size of 51, which is a a large sample.
- Also, the population standard deviation is known.
- Thus, we use the z-statistic when testing a hypothesis about a single mean.
- Formula:
where is the sample mean,
is the population mean,
is the population standard deviation and n is the sample size.
