Step-by-step explanation:
Let X be the exam scores of all applicants at a large university
X is given to be N(300, 70)
Applicants must score 230 or more on the exam before they are admitted
i.e. proportion of all applicants taking the exam is granted admission
=![P(X\geq 230)\\= 0.841345](/tpl/images/0528/9553/5c62f.png)
=0.8413
Nearly 84.13% of applicants applied are granted admission.
b) proportion of all applicants will score 440 or higher on the exam
=![P(X\geq 440)\\=0.02275\\=0.0228](/tpl/images/0528/9553/7e0fb.png)
c) No of applicants = 2400
Admission to the university =0.8413 *2400
= 2019.12
