Question

1. Is there any relationship between the type of claim and education level? (clue: X-squared = 12.336, df = 16, p-value = 0.7206)

2. Is there any relationship between the type of claim and fraudulent claims? (clue: X-squared = 12.336, df = 16, p-value = 0.7206)

3. Is there any relationship among the type of claim, fraudulent claims, and retired status? (clue: X-squared = 29.996, df = 4, p-value = 4.903e-06)

4. Is there any relationship among the marital status, fraudulent claims, and gender? (X-squared = 0.25201, df = 1, p-value = 0.6157)

For each of these questions, please provide the following: R code, output, and your interpretation and conclusion.

Answer 1

1. As p-value = 0.7206 > 0.05, so we fail to reject the null hypothesis.

There is no relationship between the type of claim and education level.

--

2. As p-value = 0.7206 > 0.05, so we fail to reject the null hypothesis.

There is no relationship between the type of claim and fraudulent claims.

--

3. As p-value = 0.000 < 0.05, so we reject the null hypothesis.

There is a relationship among the type of claim, fraudulent claims, and retired status.

--

4. As p-value = 0.6157 > 0.05, so we fail to reject the null hypothesis.

There is no relationship among the marital status, fraudulent claims, and gender.
