Statistics question
hello!

I am wondering if you could please explain these questions to me please.

Q1.
Count the fraction of samples from the forest fire data where loge(area) lies between 0 and 2.

Does this literally mean count the fractions in log form between 0 and 2?

So an example, if there are 200 number and 1 is between 0 and 2. In fraction form would I answer it as 1/200. Is that what they are asking?

Q2.
Assuming that loge(area) follows a Normal distribution with a population mean and population
standard deviation equal to the mean and standard deviation from part (i),
find the probability
that a randomly sampled value from the population of loge(area)
will be between 0 and 2.

I don't understand this question, would it be the same as question 1?

Q3.
Is there a difference in the previous two answers? Explain why.

I don't think there will be a difference.
fraction is not an entire number
probability is something probable

If you could kindly help thanks heaps!

It would be most helpful here if we could see the data set.
