Answer:
length = 30 cm
Breadth = 10 cm
Step-by-step explanation:
Length = x cm
Breadth = (1/3)x
Perimeter = 80 cm
2(length + breadth) = 80
2* (x + (1/3)x) = 80
x = 30cm
length = 30 cm
breadth = cm
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.
