A market research firm tests whether the proportion of online shoppers who prefer subscription-based purchasing models differs from 50% (H0:p=0.50, H1:p≠0.50). A random sample of n=1,000 online consumers finds that 650 prefer subscription models (p^=0.65). Using a two-tailed proportion z-test at α=0.05, the Stats Kingdom calculator returns a test statistic of z=9.4868, critical values of ±1.9600, and a p-value of 0.0000. Which of the following correctly states both the comparison that leads to the statistical decision AND the conclusion that properly follows from it?
