Question 1135839
<font face="times" color="black" size="3">
Consult a Z table such as <a href="http://users.stat.ufl.edu/~athienit/Tables/Ztable.pdf">this one</a>. Such tables are found in the back of your textbook in the appendix section. 


Using the table I linked, you will first go to the row that starts with 1.1 (scroll to the second page). Mark everything in this row. I've done so using a red box. Do the same thing for the column that has "0.03" at the top. I've used a blue box here.

The intersection of this row and column has the value 0.8708


This is the area under the standard normal bell curve that is to the left of Z = 1.13


This area also represents the probability of getting a Z value smaller than 1.13


Answer: <font color=red size=4>0.8708</font> (answer is approximate)
