Answer:
58°
Step-by-step explanation:
<h3>Angle sum property of triangle:</h3>
The sum of all angles of a triangle is 180°.
x + 69 + 55 + x + 78 = 180
x + x + 69 + 55 + 78 = 180
Combine like terms,
2x + 202 = 180
Subtract 202 from both sides,
2x = 180 - 202
2x = -22
Divide both sides by 2,
x = -22/2
x = -11
∠A = x + 69
= -11 + 69
Answer: 60%
Step-by-step explanation:
According to the hypothesis test, the correct statement of the p-value is mean value is against null hypothesis.
Hypothesis test:
In statistics, hypothesis test means a form of statistical inference that uses data from a sample to draw conclusions about a population parameter or a population probability distribution.
Given,
Here we need to find the correct statement of the p-value for the a hypothesis test for population proportion, you calculated the p-value is 0. 01 for the test statistic.
While we looking into the given question we have identified the value of p value of the test statistic is 0.01.
Then the correct statement of the p-value less than 0.01 will under normal circumstances mean that there is substantial evidence against the null hypothesis.
