Answer:
the most conservative hypothesis is
<em>H₀</em>: <em>p</em> = 0.18, <em>Hₐ</em>: <em>p</em> > 0.18.
Step-by-step explanation:
The researcher wants to test whether the rate of smoking among adults in Chicago is greater than the national rate of 18% or not.
The hypothesis for this test can be defined as follows:
Null Hypothesis (): The rate of smoking among adults in Chicago is same as the national rate, i.e. <em>p</em> = 0.18.
Alternate Hypothesis (): The rate of smoking among adults in Chicago is greater than the national rate, i.e. <em>p</em> > 0.18.
So the most conservative hypothesis is <em>H₀</em>: <em>p</em> = 0.18, <em>Hₐ</em>: <em>p</em> > 0.18.

Step-by-step explanation:
Using the cofunction identities
tan(90 - A) = cotA and cscA = sec(90- A)
Consider the left side
tanA + tan(90 - A)
= tanA + cotA
= +
=
=
= ×
= secA × cscA
= secA. sec(90 - A) = right side ⇒ verified
