WebFind the critical value of t for a 90% confidence interval with df=59. (Round to two decimal places as needed.) Question: Find the critical value of t for a 90% confidence interval … WebTranscript. If we want to be 95% confident, we need to build a confidence interval that extends about 2 standard errors above and below our estimate. More precisely, it's actually 1.96 standard errors. This is called a critical value (z*). We can calculate a critical value z* for any given confidence level using normal distribution calculations. WebPlease find the critical values, the T value, the P value, and determine if you should reject or fail to reject the hypothesis and why.
