Answer:
<u>Type I error: </u>D. Reject the null hypothesis that the percentage of adults who retire at age 65 is less than or equal to 62 % when it is actually true.
<u>Type II error: </u>A. Fail to reject the null hypothesis that the percentage of adults who retire at age 65 is less than or equal to 62 % when it is actually false.
Step-by-step explanation:
A type I error happens when a true null hypothesis is rejected.
A type II error happens when a false null hypothesis is failed to be rejected.
In this case, where the alternative hypothesis is that "the percentage of adults who retire at age 65 is greater than 62%", the null hypothesis will state that this percentage is not significantly greater than 62%.
A type I error would happen when the conclusion is that the percentage is greater than 62%, when in fact it is not.
A type II error would happen when there is no enough evidence to claim that the percentage is greater than 62%, even when the percentage is in fact greater than 62% (but we still don't have evidence to prove it).
This is division. Let’s set up your problem.
I prefer not using mixed numbers. Instead we’ll use 14/3 for the fraction.
So to start off:
14/3 / 7
the 7 can also be 7/1.
use the saying, “keep, change, flip.”
keep the 14/3, change the sign to multiplication, and flip the last fraction.
14/3 x 1/7
now multiply.
14/21 is your fraction. Now simplify.
You get 2/3.
Your answer is:
She should cut the ribbon 2/3 m.
D bc I need to answer this in order to use Brainly the app so I’m not even sure ik the answer but I just said sum
Answer:
120 cm
Step-by-step explanation:
1/2 is 6 months and 6 years are 72 months.
Using the rule of three, 10 cm is to 6 months what x is for 72 months so
x = (72 * 10) / 6 = 120
