The proportion of all high school students who watch national news is p=0.57. A random sample of 60 high
school students is selected. Which of the following is the correct calculation and interpretation of the standard
deviation of the sampling distribution of β ?
a. σₚ∧=0.004. In SRSs of size 60, the sample proportion of high school students who watch the national news typically varies 0.004 from the true proportion, p=0.71.
b. σₚ∧=0.064. In SRSs of size 60, the sample proportion of high school students who watch the national news typically varies 0.064 from the true proportion, p=0.71.
c. σʙ=0.245. In SRSs of size 60, the sample proportion of high school students who watch the national news typically varies 0.245 from the true proportion, p=0.71.
d. σʙ=0.570. In SRSs of size 60, the sample proportion of high school students who watch the national news typically varies 0.570 from the true proportion, p=0.71.
