Set up hypotheses:
The null hypotheses is that the proportion of readers who own a Rolls Royce is equal to 0.55
Null hypotheses = H₀: p = 0.55
The alternate hypotheses is that the proportion of readers who own a Rolls Royce is not equal to 0.55
Alternate hypotheses = H₁: p ≠ 0.55
Determine the type of test:
Since the alternate hypothesis states that the proportion of readers who own a Rolls Royce is different, therefore it is a two-tailed test.
Determine the level of significance and Critical Z-score:
Given level of significance = 0.05
Since it is a two-tailed test,
Z-score = 1.960 (two tailed)
Set up decision rule:
Since it is a two-tailed test, using a Z statistic at a significance level of 5%
We Reject H₀ if Z < -1.960 or Z > 1.960
We Reject H₀ if p ≤ α
Compute the test statistic:
The test statistic may be calculated using,
We are not given enough information to find out the test statistic.
Conclusion:
We do not have enough information to accept or refuse the publisher's claim.
Draw the DE ray away from the BAC angle is the next step to copy the BAC angle
<h3>Further explanation </h3>Angles can be formed from two ray lines that have the same starting point
Commonly used terms include foot angle, corner point, and angle size
The magnitude of the angle is usually expressed in degrees
Naming angles can be with one letter according to the vertex or with three letters with the vertex placed between two other letters
There are several steps used to copy the BAC angle:
- 1. Draw the DE line
- 2. Draw a circle using the circle tool with center A. The circle will intersect the lines BA and BC at points F and G
- 3. Use the segment tool to create a segment from the circle radius that has been created
- 4. Use the Compass tool and select the segment from the AG radius
- 5. Make a circle with center point D, with the same radius as AG
- 6. Mark the intersection of the circle with the intersection of the DE as H
- 7. Create the FG segment, and use the compass tool to select the FG segment
- 8. Create a circle with center H, which will intersect the circle with center D earlier at the point I
- 9. Draw the DI line
Then the BAC is congruent to the HDI
