Answer:
represent the random sample selected
represent the number of pots that were bare ground (no vegetation

And replacing we got:

So then the sample proportion of bare ground spots is 0.792 for this sample
Step-by-step explanation:
We have the following info given from the problem:
represent the random sample selected
represent the number of pots that were bare ground (no vegetation)
And for this case if we want to find the sample proportion of bare ground spots we can use this formula:

And replacing we got:

So then the sample proportion of bare ground spots is 0.792 for this sample
we are asked in the problem to simplify the expression (1/64) ^ -2/3 * 25 ^ -3/3. In this case, the first step is to separately determine the values of (1/64) ^ -2/3 and 25 ^ -3/3 and then multiply the values. This is equal to 16 * 1/25 equal to 16/25.
