A sociologist wants to study what proportion of people have significant relationship problems due to financial stress. A previous study she is aware of estimated it to be 32% but she believes this has increased in modern times. She collects a random sample of 150 people and 63 of them report relationship problems due to financial stress. Conduct an appropriate hypothesis test in questions #22-#25. Choose the correct alternative hypothesis for this test. A)p ≠ 0.32 B)p = 0.32 C)p > 0.32 D)p < 0.32
