Answer:
Critical Value
Step-by-step explanation:
The critical value separates the region of rejection from the region of non rejection.
We define critical values as:
- Critical value helps us to give the decision rule for the rejection or acceptance of null hypothesis.
- Critical value separates the acceptance region from the rejection region.
- These are referred to as cut-off values that define regions where the test statistic is unlikely to lie.
- The critical value depends on the kind of test being performed and the significance level.
Answer:
5.6 gallons.
Step-by-step explanation:
If we take x gallons of 25% grape juice then it will contain 
gallons of pure grape juice.
Again, if we take y gallons of 75% grape juice then it will contain 
gallons of pure grape juice.
If we mix them then the total volume will become x + y = 7 gallons ...... (1)
Again the mixture will become 35% juice.
So, 
⇒ 0.25x + 0.75y = 0.35x + 0.35y
⇒0.1x = 0.4y
⇒x = 4y........ (2)
Now, solving equations (1) and (2) we get, 5y = 7, ⇒ y = 1.4 gallons
Hence, x = 4y = 5.6 gallons
Therefore, the 25% grape juice was mixed by 5.6 gallons. (Answer)

Answer:
$6932
Step-by-step explanation:
Let last year's sales = x. Since there was a decrease of 5%, that means this year's sales are 95% of last year's sales.
So, .95x = 6585
x = 6932 to the nearest dollar
