I Might know what your talking about. . . .if so then it is A) 40 degrees
48 students in group 2
43 students in group 1
So in total there are 91 students
7 students play the trump

Answer: 95% certain that true proportion of population "p" is contained in (0.604, 0.781)
Step-by-step explanation:
We know that a 95% confidence interval is a range of values that you can be 95% sure that true mean of the population or true proportion of population lies in it .
Given : The 95% confidence interval for p was calculated to be (0.604, 0.781).
It means that we are 95% certain that true proportion of population "p" is contained in (0.604, 0.781).
Hence, the correct interpretation for this interval :- 95% certain that true proportion of population "p" is contained in (0.604, 0.781).
