1:17 let's say we're dealing with a 95% confidence level, you can use the standard z table to get the critical value to decide whether you would accept or reject the null hypothesis you need to get another z value, a calculated z value, and compare it to critical value 1:58 if Zc is to the right of z, then that means you should reject the null hypothesis
