In this question, we given a piece-wise function, that has different definitions depending on the domain.
Evaluate the function at x = 0.
The exercise asks for us to evaluate the function at
We have to look at the definition, and see which definition includes . The equal sign at
is on the second definition, that is:
Thus, at , the value of the function is 1, and the correct answer is given by option A.

Answer:
On this case since the p value is less than 0.05 then the results are significant. So then Joshua can say that the t-test conducted is significant. And on this case makes sense report the effect size.
Step-by-step explanation:
Effect size is defined as a "quantitative measure of the magnitude of the experimenter effect". If we have a high value for the effect size then we can conclude that we have a stronger relationship between two variables.
t-test: Is used to compare group means. Is one of the most common tests and is used to determine whether the means of two groups are equal to each other.
The independent t-test, is an statistical test in order to determine if we have statistically significant difference between the means of two unrelated groups.
We can check for example the following hypothesis:
Null hypothesis:
Alternative hypothesis:
The statistic for this test is given by:
(1)
The value obtained after apply the formula (1) was 10.25.
And the degreed of freedom are calculated from:
On this case since the p value is less than 0.05 then the results are significant. So then Joshua can say that the t-test conducted is significant. And on this case makes sense report the effect size.
Usually when the Cohen effect size value d=0.2 or lower we can consider this as a 'small' effect size, and that's our case.
