Answer: This is an reduction.
Step-by-step explanation:
- A dilation a king of transformation that creates an similar image (about a center of dilation) of the actual figure by changing its size with the use of a scale factor(k).
- It either shrinks or stretches the image.
- If |k| is greater than 1 then the image is an enlargement .
- If |k| is less than 1 then the image is an reduction.
- If |k| is equals to 1 then there is no change in size.
Given : A street is drawn by dilating segment about center A with a scale factor greater than 0 but less than 1.
Then by using (2.) , we can say that this is an reduction.
Using the t-distribution, it is found that the test statistic for the hypotheses test is given by:
At the null hypotheses, it i tested if the mean difference remains the same, that is:
At the alternative hypotheses, it is tested if it has decreased, hence:
.
The test statistic is given by:
The parameters are:
is the sample mean.
is the value tested at the null hypothesis.
- s is the standard deviation of the sample.
- n is the sample size.
The parameters are given as follows:
.
Hence the test statistic is given by:
