Question 21
students, 61 respond they have limited or no access to internet at home.
Q. According to this sample, what is the point estimate for p, the proportion of all students who have limited or no access to the home internet?
Estimate for p=
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?
Option A. Yes, the sample size is greater than 30.
Option B. Yes, n\times p_(0)>=10 and n\times (1-p_(0))>=10
Option C. Yes, the population standard deviation is known.
Option D. No, the population mean is unknown.
Indicate the correct option:
Q. The p-value for the hypotheses: H_(0):p=0.15 and H_(a):p!=0.15 is
