You are conducting a study to see if the accuracy rate for fingerprint identification is significantly different from 0.51. You use a significance level of a = 0.001. Ho:p = 0.51 H₁:p 0.51 You obtain a sample of size n = 373 in which there are 169 successes. What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is... O less than (or equal to) a greater than a This p-value 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...
