Answer:
Step-by-step explanation:
Let
n------> a number
we have
n represent the 100%
so
by proportion
The y-intercept has to be close to 10 because that's the one closest to the point closest to the y-axis. Therefore it has to be the last one.
Hope this helps :)
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).
Answer: 180.
Step-by-step explanation:
Appetizers = 5 types
drinks = 3 types
Sandwiches = 4 types.
Solution:
This is a combination problem.
For appetizers
= 5C2
= 10.
For drinks
= 3C2
= 3.
For sandwiches
= 4C2
= 6.
No. Of combinations scot can choose for his party
= 10*6*3
= 180
Scot can choose a total of 180 combinations for his party.
