1.) The proportion of residents in Phoenix favoring the building of toll roads to complete the freeway system is believed to be p=0.3. If a random sample of 100 individuals shows that 25 favor building toll roads, do we have evidence at the 5% level to claim the true proportion is really lower? Show all work! Step 1: Step 2: Step 3: Step 4: Step 5: P-value: Step 6 Step 7:
