Answer:
A
Step-by-step explanation:
We can write this as Sinx by "flipping" the .
So we will have:
From basic trigonometry, we know the value of of sine is of the angle
<em>But when is sine negative? </em>Either in 3rd or 4th quadrant. But the answer has to be between 0 and , <em>so we disregard 4th quadrant.</em>
<em />
<em>To get the angle in 3rd quadrant, we add π to the acute angle of the first quadrant (which is π/4 in our case).</em><u><em> Thus we have:</em></u>
A is the right answer.
In this scenario, the parameter is the sample proportion, which is of 0.7.
<h3>What is the parameter?</h3>
- When a hypothesis is tested, the parameter is the information obtained from the sample, mean or proportion.
- In this case, it is the <em>sample proportion</em>, which is the <u>number of desired outcomes divided by the number of total outcomes</u>.
She goes to the correct object in 70 of those 100 trials, hence:
The parameter is the sample proportion, which is of 0.7.
