Question
Please help with the question. I’m not sure why my anwere are wrong. I’m stuck. It's a statistics question.
You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly different from 0.12. You use a significance level of a = 0.10. Ho:p= 0.12 H1:p# 0.12 You obtain a sample of size 295 in which there are 20 successes. What is the test statistic for this sample? (Report answer accurate to 3 decimal places.) What is the p-value for this sample? (Report answer accurate to 4 decimal places.) This test statistic leads to a decision to O reject the null O accept the null O fail to reject the null As such, the final conclusion is that O there is sufficient evidence to conclude that the probability of a true negative on a test for a certain cancer is different from 0.12. O there is not sufficient evidence to conclude that the probability of a true negative on a test for a certain cancer is different from 0.12. O there is sufficient evidence to conclude that the probability of a true negative on a test for a certain cancer is equal to 0.12. O there is not sufficient evidence to conclude that the probability of a true negative on a test for a certain cancer is equal to 0.12.
