Answer with explanation:</h2>
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.

Answer:
3.5 or 3 and 1/2
Step-by-step explanation:
3 and 15/16 / 1 and 1/8
Step-by-step explanation:
- <em>-x-4=</em><em>4</em><em>x</em><em>-</em><em>5</em><em>4</em>
Adding x on both sides, we get
- <em>-x-4+</em><em>x=</em><em>4</em><em>x</em><em>-</em><em>5</em><em>4</em><em>+</em><em>x</em>
- <em>-</em><em>4</em><em>=</em><em>5</em><em>x</em><em>-</em><em>5</em><em>4</em>
Adding 54 on both sides, we get
- <em>-</em><em>4</em><em>+</em><em>5</em><em>4</em><em>=</em><em>5</em><em>x</em><em>-</em><em>5</em><em>4</em><em>+</em><em>5</em><em>4</em>
- <em>5</em><em>0</em><em>=</em><em>5</em><em>x</em>
Dividing both sides by 5, we get
- <em>5</em><em>0</em><em>/</em><em>5</em><em>=</em><em>5</em><em>x</em><em>/</em><em>5</em>
- <em>1</em><em>0</em><em>=</em><em>x</em>
<em>Hence,</em><em> </em><em>the </em><em>value</em><em> of</em><em> x</em><em> </em><em>is</em><em> </em><em>1</em><em>0</em><em>.</em>
