Set up two inequalities for the absolute value inequality.
First inequality and second inequality: x + y > 1 or x + y < -1
Notice I used or between the inequalities. If your absolute value expression is greater than the constant, it is a disjunction.

Graph the individual inequalities on the same plane and that is your solution.

A marketing study conducts 60 significance tests about means and proportions for several groups. Of​ them, 3 tests are statistic
Sav [38]

Answer:

hello your question lacks the required options attached is a picture of the complete question

One would expect about 5% of tests to be significant just by chance if the null hypothesis is true, and for 60 tests, this is 0.05(60) = 3 tests. This could explain why these tests are statistically significant.

Step-by-step explanation:

What is misleading about this is the study's final report because this marketing study was carried out with a level of significance of 5% (0.05) which means that if we carry the same study with varying sample data we will mostly like arrive at a conclusion against our null conclusion 5% of the time and this is not good for the the study because it is a type 1  error and has to be eliminated and it cannot be eliminated totally .

hence  One would expect about 5% of tests to be significant just by chance if the null hypothesis is true, and for 60 tests, this is 0.05(60) = 3 tests. This could explain why these tests are statistically significant.
