Answer:
And we can use the following excel code to find it:"=2*(1-NORM.DIST(4.21,0,1,TRUE)) "
With the p value obtained and using the significance level assumed for example we have
so we can conclude that we have enough evidence to reject the null hypothesis, and we can said that at 5% of significance the percentage 1 is significantly different from the percentage 2.
D) Are statistically different.
Step-by-step explanation:
The system of hypothesis on this case are:
Null hypothesis:
Alternative hypothesis:
Or equivalently:
Null hypothesis:
Alternative hypothesis:
Where and
represent the percentages that we want to test on this case.
The statistic calculated is on this case was Z=4.21. Since we are conducting a two tailed test the p value can be founded on this way.
And we can use the following excel code to find it:"=2*(1-NORM.DIST(4.21,0,1,TRUE)) "
With the p value obtained and using the significance level assumed for example we have
so we can conclude that we have enough evidence to reject the null hypothesis, and we can said that at 5% of significance the percentage 1 is significantly different from the percentage 2.
And the best option on this case would be:
D) Are statistically different.
The measure of an angle is the coterminal angle with a 45A°+360A° and can be determined by using the measurement of coterminal angles.
<h2>We have to determine</h2>Which expression finds the measure of an angle that is coterminal with a 45° angle?
<h3>According to the question,</h3>Coterminal angles are those angles that share the terminal side of an angle occupying the standard position.
The standard position means that one side of the angle is fixed along the positive x-axis, and the vertex is located at the origin.
<h3>A coterminal with 45° is 45°+k°360° with k as an integer.</h3>Then,
The coterminal angle with 45°,
When k = 0
Then,
When k = 1
Then,
When k = -1
Then,
Hence, The measure of an angle that is coterminal with a 45A°+360A°.
