A researcher analyzes the last digits of lottery ticket numbers in a city and finds that among $1500$ randomly selected digits, $175$ are sevens. If the digits are randomly distributed, the proportion of sevens should be $0.1$. Use the critical value method with a $0.05$ significance level to test the claim that the proportion of sevens equals $0.1$. What is your conclusion?

• A. There is insufficient evidence to reject the claim that the proportion of sevens is $0.1$
• B. There is sufficient evidence to reject the claim that the proportion of sevens is $0.1$
• C. There is sufficient evidence to support the claim that the proportion of sevens is $0.1$
• D. The sample proportion is significantly greater than $0.1$, but the test is inconclusive due to an insufficient sample size

Answer: (B)
