A researcher wants to determine whether there is a relationship between age and frequency of travel. In a random sample of 18- to 25-year-olds, 70 of 195 traveled more than twice each year. In a random sample of 55- to 62-year-olds, 205 of 230 traveled more than twice each year. What is the margin of error for a 98% confidence interval for the difference between the proportions of travelers in these age groups who travel more than twice each year?

Answer:
C. 0.0931
Explanation:
The margin of error for a 98% confidence interval for the difference between the proportions of travelers in these age groups who travel more than twice each year is 0.0931.
What is margin of error?Margin of error is defined as the level of error in survey findings that were chosen at random. Your results will vary from the actual population value by how many percentage points, as indicated by the margin of error. In statistics, the margin of error is the level of inaccuracy in the findings of surveys using random samples.
If your statistic has a 95% confidence interval and a 4% margin of error, it will often be within 4% of the true population value and if it is 98% and a 5 % margin of error is occurred according to this the answer is 0.0931.
Thus, the margin of error for a 98% confidence interval for the difference between the proportions of travelers in these age groups who travel more than twice each year is 0.0931.
