Evidence suggests the proportion of voters who favor stricter gun control laws is not 0.48 and has actually increased. O b. The percentage of voters who favor stricter gun control laws could still be 48%, but the actual population percentage is still unknown. Oc. The percentage of voters who favor stricter gun control laws is still 48%. O d. No conclusion is possible based on the information given.
