<h2>The answer is 1</h2>
Step-by-step explanation:
First of all transform the expression using trigonometric identities
That's
So we have
Reduce the expression with tan x
We have
Reduce the expression with cos x
That's
Reduce the expression with sin x
We have
We have the final answer as

An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 220 engines and the mean pressure was 5.4 pounds/square inch (psi), the level of significance for the hypothesis test is 0.05. This is further explained below.
<h3>What is the level of significance?</h3>
Generally, the level of significance is simply defined as statistical analysis, the significance level is defined as the likelihood of rejecting the null hypothesis when it is correct.
In conclusion, The average pressure throughout testing on 220 engines was 5.4 psi, and the significance threshold for the hypothesis test was set at 0.05.
