Suppose that the insurance companies did do a survey. They are interested inthe population proportion of drivers who claim they always buckle up with 95%confidence. Their estimate must be accurate within 2% of the true proportion.i.If no preliminary estimate is available, find the minimum sample sizerequired.ii. Find the minimum sample size needed if they randomly surveyed 400drivers and found that 320 claimed they always buckle up.
