Hi, i am having a little problem with statistics

QUESTION 7 Suppose that n = 55. i.i.d observations for (W Xi} yield the following regressions results: ?= 49.2 + ?3.9X. SER = 13.4. R2 = 0.?8 {23.5} {16.4} Another researcher is interested in the same regression. but makes an error when entering the data into a regression program: The researcher enters each observation twice. ending up with 100 observations {with observation 1 entered twice, observation 2 entered twice and so forth). Using these 100 observations, what results will be produced by the regression program? Complete the spaces in the equation below. Report the intercept and slope to one decimal place. but report the R2 to two decimal places. t: 49.2 + 73.9 *x, R2: 0.?8 QUESTION 8 In Question 7, which (if any) of the following internal validity conditions are violated? O Omitted variable bias O Wrong functional form bias O Errors-in-variables bias O Simultaneous causality bias O None of the above interval validity conditions are violated
