Answer:
you are left with 1/2
Step-by-step explanation:
1/3+ 1/6= 3/6 =1/2
Answer:
6/12
1/2
Step-by-step explanation:
First, we need to find how many multiples of three there are, and how many numbers less than three there are on a 12 sided die.
Multiples of 3: 3, 6, 9 ,12
Less than 3: 2, 1
When calculating the probability of rolling a number, the actual number is arbitrary- instead, you need to know how many of numbers exist to fit the requirements. In this case, it's 6 total. Since there's 12 possibilities on a 12 sided die, the probability would be 6 out of 12. You could also simplify the fraction, but both are equivalent.
I hope this helps!
Answer:
Null Hypothesis,
: p
85%
Alternate Hypothesis,
: p > 85%
Step-by-step explanation:
We are given that it's been found that 85% of American adults suffer from triskaidekaphobia (fear of the number 13).
A USA Today/Gallup poll asked 1,006 randomly selected people 18 years old and older in telephone interviews "Suppose you checked into a hotel and were given a room on the thirteenth floor. Would this bother you or not?" 87% of the survey respondents answered they would be bothered.
Let p = <u><em>proportion of respondents who would be bothered about given a room on the thirteenth floor</em></u>
SO, Null Hypothesis,
: p
85%
Alternate Hypothesis,
: p > 85%
Here, <u>null hypothesis states that</u> the proportion of respondents who would be bothered about given a room on the thirteenth floor is less than or equal to 85%.
On the other hand, <u>alternate hypothesis states that</u> the proportion of respondents who would be bothered about given a room on the thirteenth floor is more than 85%.
Hence, this would be the correct null and alternative hypothesis.
