   Question

   A teacher is interested in how the number of hours that students have studied (“HOURS”) on the score on a particular test (“SCORE”). He conducts a regression analysis with these two variables, using data from a sample of 160 students.

   This leads to the following linear model: SCORE = 2.30 + 0.80 * HOURS.

   The teacher wants to determine whether UREN has a positive influence on SCORE. He tests two-way with a 5% significance level (α = 0.05). What should the teacher test in this case?

   
   
   1. FALSE: He should check whether the value 0.80 is significantly different from 0.00.
   2. TRUE: He should check whether the value 0.80 is significantly different from 0.05.
   3. FALSE: He must verify that the value 0.80 is significantly different from 0.025.
   4. FALSE: He must verify that the value 0.80 is significantly smaller than 0.95.
   5. FALSE: He must verify that the value 0.80 is significantly smaller than 1.96.
   
   
   1. False
   2. True
   3. False
   4. False
   5. False
