Answer:
Number of students ; 60
Explanation:
Using the formula for p +- z * Sqrt ( pq/n )
Let us first calculate the Margin of Error
= 0.816 –0.7 = 0.116
•z* = 1.96
P = (0.584 + 0.116 ) = 0.7
Q = 1- p = 1 – 0.7 = 0.3
Now inserting the values in the formula; we get
0.116 = 1.96 x sqrt { ( 0.7 x 0.3) / n }
Solving the above equation
N = 60 (rounded off to nearest number)
Hence the number of students that were selected by the environmental teacher in the sample is 60
Answer
D. Rent textbooks
Explanation
Textbook rental from Chegg allows students to rent books and save money on their college books. Here a student can rent a textbook required by the lecturers and alter return it for free when done. Chegg offers lower charges for renting books than purchasing the book from stores.
B. Weighted GPA
You see the unweighted is considered the college GPA and removes all AP, IB, or Honors clasess and puts all college applicants on the same level, cumulative GPA is wrong and doesn't make any sense with relation to the question, and the semester GPA wouldn't technically include the extra 10 points that these classes give.
