I the average score is 750 and standard deviation ( sigma ) is 50 points, then score 700 - 800 is between (750 - 1 sigma) and (750 + 1 sigma).
That is 34.1 % + 34.1 % = 68.2 % of the whole population.
2,000 · 0.682 = 1.364
We expect 1,364 students to score between 700 and 800 points.

Step-by-step explanation:
The cost of next model car is $ 33136.
Step-by-step explanation:
Given,
The cost of current model car is $38000
The next model car is 12.8% less than the current model.

If the price of object is $x and it decreases r% for next year, the value o the object for next year is = $ x×(100-r)%
So,
The cost of next model = $ 38000×(100-12.8)%
= $ 38000×87.2%
= $ 33136
