Answer:
elsa's interval width will be greater than that of frank
Step-by-step explanation:

now as the confidence level goes higher, so also would the margin of error increase. then the width of the confidence interval would rise so it can be more confident.
from this question elsa has a larger confidence level therefore her intervals width will be greater than franks own.

or y=(x+2)²+0
vertex Is (-2,0)
It would be: 255 - (255 * 22%)
= 255 - (255 * 0.22)
= 255 - 56.1
