In this question, we have given that on SAT, average writing score is 486 points and average mathematics score is 522 points. The standard deviation for each part is 85 points on each part of the test. No. of students selected for testis 36.

Step 2

On the basis of calculations shown on the whiteboard we have got that writing score must be at least 514.645 to get the 97% of the data lie below than that.

The value of Z where 97% of the data lies below than t...
