Population is the MBHS students
Parameter is % who text in class at least 10 times a week
270 students were the sample
margin of error is 1.96*sqrt(p*(1-p)/n)=1.96 * sqrt (0.659*0.341/270)=0.057 or 5.7%
95% interval is (0.602, 0.716)
I don't know what the exact value is for the entire population, but I am 95% confident it lies in the interval above.
