Here are my numbers from my confidence interval: From R: MSE=.9077103, s2{b1}= 3.104238e-05, s{b1}= 0.005571569 Confidence interval: b1±t(1-α/2,n-1) s{b1} 18.02830±t(1-.02/2,12-1)(0.005571569) =18.02830±(2.718)(0.005571569) (18.01316, 18.04344) Could someone check to see if this is...

So in other words, I am testing: Ho: β1=17.50 Ha: β1≠17.50 ?

Homework Statement Okay, so the problem I have goes like this: Shown below are the number of galleys for a manuscript (X) and the total dollar cost of correcting typographical errors (Y) in a random sample of recent orders handled by a rime specializing in technical manuscripts. Since Y...

Hi Ray, What I am not understanding is how you have t-theta+theta and then in the next step just eliminated that down to theta outside of the integral. I just need to understand your thinking behind it because it doesn't make sense to me. Thanks!

Hi Ray, I am not understanding how you went from ∫tf(t-θ) to what you have presented below. Could you provide further details in the steps you have listed below? Also, should have I made my integral from theta to infinity instead of 0 to theta? Thanks!

So I am struggling with this homework problem because I got burned out of another problem earlier today, and I just cannot get beyond what I have. The problem is: Let X be a continuous random variable with the pdf: f(x)=e^(-(x-θ)) , x > θ , and suppose we have a sample of size n ...

This is my first topic post here, so here it goes. :) I am hoping that someone out there can answer this question that I have about going to graduate school for Statistics or even for Mathematics in general. I am starting to look at schools for graduate school, but I am starting to get...

I really wish I could hug you. You have just helped me to know that I'm not the only one in this world that feels like you. I am just starting my third year in my undergrad mathematical career, and I'm going through my Intro to Proofs class and feeling like a complete failure. I do fabulous on...
