Answer:

02 High Schools would be selected from the stratum with a​ percent-free-lunch value of 40 less than or equals x​.

Step-by-step explanation:

As the sample size needed is 25 and total schools are 100 so this indicate 1 school in each 4 schools is to be selected. This is given as

n=\frac{n_{total}}{n_{sample}}\\n=\frac{100}{25}\\n=4

Now as the schools with percent free lunch are 8 so now

n=\frac{n_{total}}{n_{sample}}\\n=\frac{8}{2}\\n=2

So only 2 schools will be selected in this regard.
