At a campus writing center, a random sample of 750 appointment records found 236 cases in which the student uploaded a draft in advance. Let p be the true proportion of comparable cases with that outcome. A baseline claim states p0 = 0.35 (35%). Test H0: p = 0.35 against Ha: p > 0.35. Assume the one-sample z conditions are reasonable. A report will summarize the test at alpha = 0.10. Which statement reports the calculation without overstating the result? Round SE to four decimals, z to two decimals, and the p-value to three decimals.
