Hi, I need a bit more help for page 3 part d,
Fo the 95% CI whaat formula did you used to find S and can you do step by step for the other parts I don't understand it...
t(alpha/2) and Mx what's these??

Yo +- t(alpha/2)*SE*sqrt(1/n +(Xo-Mx)^2/(n-1)*S^2x

Picture
Expert:  Trigeoscal replied 288 days and 6 hours ago.

s here is the standard deviation of the x variable, its formula is

s = sqrt [summation of (x - mean)^2 / (n-1)]

in what specific page are you referring to that you want a more detailed explanation?

Customer replied 288 days and 6 hours ago.

Page 3 please part d

Picture
Expert:  Trigeoscal replied 288 days and 6 hours ago.

Mx is the mean of X so just add all the ten values of X then divide the sum by 10 then you will get Mean of x (Mx) = 0.4951

11.93 is obtained by substituting x = 0.50 in the regression equation;


Yhat = 6.51+ 10.83x
Yhat = 6.51+ 10.83*0.50
Yhat = 11.925 or approx. 11.93


t(α/2) is the two tailed critical t value, you need to look at the t distribution table, and since n = 10, the degrees of freedom = n -2 = 10 - 2 = 8, so at alpha = 0.05 (two tailed) and df = 8, the critical t value at the t table is t = 2.306

Sx is the standard deviation of the x variable,

to compute for it, subtract each score in the x variable by the mean of x, then after that, square each differences, then get the sum of the squared differences, then divide the sum by n - 1 = 10 - 1 = 9, then finally get the square root of the quotient, you will get a value of Sx = 0.0648

also you can use scientific calculator (SD mode) in computing standard deviation or even excel (just use the function =stdev( then select all the scores in the x variable) then press enter

Customer replied 288 days and 6 hours ago.

Thanks for clarifying it out, I understand now.
And how a you going with page 5, could you also resend page 1 it didn't work
Thanks
