Feb 18, 2013 · 1 Critical points are not where the function is $0.$ You want to find the points where the derivative is $0.$ Unfortunately, your function does not happen to be differentiable at $2$ or $-2,$ so …

Nov 20, 2010 · Alright, I'm trying to figure out how to calculate a critical value using t-distribution in Microsoft Excel... ex. a one-tailed area of 0.05 with 39 degrees of freedom: t=1.685 I know the …

Sep 20, 2018 · Find the critical value $t_ {\alpha/2}$ needed to construct a $98\%$ confidence interval. I have tried everything I know how to figure out this t value for $98\%$ confidence interval and I cannot …

Nov 28, 2017 · To find these critical points you must first take the derivative of the function. Second, set that derivative equal to 0 and solve for x. Each x value you find is known as a critical number. But …

Dec 23, 2020 · My knowledge about finding critical value from a t distribution For example, if i want a t -value for a 90% confidence interval when i have 9 degrees of freedom, go to the bottom of the table, …

May 20, 2020 · In my textbook a critical value does not necessarily exist where a point of inflection is found. For instance, in this problem, a critical value does not exist at x = 2 but there is a point of …

To find the first critical value, I set the denominator equal to 0 and got the first value of 0, but I'm stuck on the last critical value. The back of the book says the critical values are 0 and 4/9.

Mar 4, 2021 · 0 I am a bit confused about what is generally done (without the help of any kind of software) to obtain critical values when exact degrees of freedom values are missing in a T-table. …

Oct 15, 2015 · To Find a critical value for a 90% confidence level. Step 1: Subtract the confidence level from 100% to find the α level: 100% – 90% = 10%. Step 2: Convert Step 1 to a decimal: 10% = 0.10. …
