Here is the question. Thanks for the help! Based on a sample of n=22...

n Based on a sample of n = 22, the least-squares method was used to develop the prediction line '?i = 8 + 2Xi. In addition, SYX = 3.2, X = 6, and z (Xi - )2) 2 = 22. i=1 Complete parts (a) and (b) below. Click here for p_age 1 of critical values of t. Click here for p_age 2 of critical values of t. 3. Construct a 90% condence interval estimate of the population mean response for X = 3. DSPYIX=3 5 El (Round to four decimal places as needed.)
