A statistics student wants to survey a high school of 910 students concerning support for increasing the number of student parking spots. The student randomly selects 90 students, and finds that 63 support increasing the number of student parking spots. Assuming the conditions for inference have been met, what is the 95% confidence interval for the true proportion of students who would support the increase in the number of parking spots? 0.30 plus-or-minus 1.65 StartRoot StartFraction 0.30 (1 minus 0.30) Over 90 EndFraction EndRoot 0.70 plus-or-minus 1.65 StartRoot StartFraction 0.70 (1 minus 0.70) Over 910 EndFraction EndRoot 0.30 plus-or-minus 1.96 StartRoot StartFraction 0.30 (1 minus 0.30) Over 910 EndFraction EndRoot 0.70 plus-or-minus 1.96 StartRoot StartFraction 0.70 (1 minus 0.70) Over 90 EndFraction EndRoot
