Given : A store owner claims that the proportion of shoppers who use coupons is less than 25%.
Then , the null hypothesis and the alternative hypothesis will be :-
, since the alternative hypothesis is left tailed , so the test is a left tailed test.
Also,t the test statistic for this hypothesis test is −1.17 and the critical value for this hypothesis test is −1.282 .
We know that when the test statistic value if greater than the critical value , then we reject the null hypothesis.
Here test statistic value(−1.17 ) is greater the critical value(−1.282) for this hypothesis , so we reject the null hypothesis.
So we conclude that there is enough evidence to support the claim.

Which of the following study design categories focuses on observing and documenting behavior?
- Several various kinds of non-experimental studies in which behavior is routinely observed and documented are collectively referred to as observational research.
- A variable or combination of variables must be described in order to be the focus of observational research.
What are some examples of biological processes that have an impact on development?
- An individual's physical makeup can alter as a result of biological processes.
- and several biological processes that have an impact on development include weight gain, changes in motor skills, puberty's hormonal changes, and cardiovascular deterioration.

Answer:
Yes, she is Correct
Step-by-step explanation:
I could prove this through writing the exponential equation that resembles this equation, but it's simpler than that:
It mentions that the population would be half of what it was before (a decade before). Now it is safe to say that every exponential (not decaying) equation gradually increases so that every value differs from it's consecutive value through multiplication of a constant.
<em>That is why, given the population would be half of what it was before, 0.5 acts as the 'constant' and the word problem can be modeled by an exponential graph + exponential function.</em>
Answer:
A regression line and trend wine are equivalent terms.
Step-by-step explanation:
The ordered pair that describes the origin is (0, 0).
That's because x=0 and y=0 at the origin.
