According to the given question the value of the Lower Bound is 0.639 and the Upper Bound is 0.762 .

What is a function's lower bound?

C is a lower bound on the roots of the equation f(x) = 0 if you divide a quadratic function f(x) by (x - c), where c 0, using synthetic division, and the result is switching signs. The fact that negative numbers can be positive or negative deserves special attention. Keep in mind that for c to be a lower bound, two conditions must hold.

Briefing:

Given That :-

X =105

n =150

CI = 90%
