Just got it done, could you check it for correctness and give some feedback if i was wrong? Thank you!

A large university would like to know if the proportion of students who have used a campus computer lab in the last month is less than 30%. They take a random sample of 265 students and ask: "This past month did you use a computer lab on campus?" Among those surveyed, 69 students say they have used a campus computer lab in past month. Q. According to this sample, what is the point estimate for p, the proportion of all students who have used a computer lab on campus in the past month? Estimate for p = 0.260 Q. In order to perform a hypothesis test for p, researchers need to check conditions, one condition being the sample is random, this condition is met. Are the other conditions met? a. No, the population mean is unknown. b. Yes, the sample size is greater than 30. c. Yes, n X po 2 10 and n X (1 - po) 2 10 d. Yes, the population standard deviation is known. Indicate the correct option here: C. Q. Perform the hypothesis test, for Ho : p = 0.30 andHa : p
