effect of galleys for a manuscript (X) on the total ...

Use the appropriate test to determine if the effect of galleys for a manuscript (X) on the total dollar cost of correcting typographical errors (Y) in technical manuscripts can be justifiably represented by a regression-through-the-origin model. Find (i) value of the test statistic, (ii) critical value at 2% level of significance, and (iii) p-value of the test. The linear regression function does through the origin, the estimated regression function is Y-hat=18.0283X. From 1, 2, 3, 4 options below, which one is correct answer?

- (i) 0.841; (ii) 15.3187; (iii) 0.7974
- (i) 0.0841; (ii) 17.0071; (iii) 0.9974
- (i) 8.41; (ii) 13.0482; (iii) 0.0734
- (i) 0.00841; (ii) 17.0071; (iii) 0.99997

Answer #1

Use the appropriate test to determine if the effect of galleys
for a manuscript (X) on the total dollar cost of correcting
typographical errors (Y) in technical manuscripts can be
justifiably represented by a regression-through-the-origin model.
Find (i) value of the test statistic, (ii) critical value at 2%
level of significance, and (iii) p-value of the test. The linear
regression function does through the origin, the estimated
regression function is Y-hat=18.0283X
