The answers would be 11, if you plug it in it would be 5(11)-7=48
It is my unprofessional opinion that the answer will be c.
my reasoning is because Lisa is asking for a percentage from a set amount<span />
A study of 600 college students taking statistics 101 revealed that 54 students received the grade of
a. Typically 10% of the class gets an A
b. The difference between this group of students and the expected value is not significant at the 0.05 level. what does this mean in this case?
Your answer would mean that, =====> The probability of getting an A is 10% and only 9% got an A, in this study. The difference is less than 5% therefore, in this case, it is not significant.
Hope that helps!!!! : )
