90% confidence interval for the true average GPA would give a wider range than a 80% confidence interval based on the same data .
Step-by-step explanation:
An
confidence interval indicates that a person can be 
confident that true population parameter lies in it.
Since Width of interval
level of Confidence interval
As level of Confidence interval increases width of interval increases.
So, More level of confidence more width of the interval.
Thus, 90% confidence interval for the true average GPA would give a wider range than a 80% confidence interval based on the same data .

Hey there! I'm happy to help!
The additive inverse is when you switch the sign. The additive inverse of 4x is -4x. A number added to its additive inverse is equal to 0.
The multiplicative inverse is also known as the reciprocal, and it is where you flip the numerator and denominator. If you multiply a number by its reciprocal, it equals 1. The multiplicative inverse 4x would be 1/4x.
The additive inverse is -4x.
The multiplicative inverse is 1/4x.
Have a wonderful day! :D
