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.

Answer: Option C: 44
Step-by-step explanation:
so, here we have the equation:
H(a,b) = 2a + 4b
"evaluate" means change the values of the variables for specific values, here we must replace the "a" for 10, and the "b" for a 6.
So we have:
H(10, 6) = 2*10 + 4*6 = 20 + 24 = 44
Answer:
We are given a rectangular lot with dimensions 72.2 feet long and 50 feet wide.
1. To find the size of the park, we need to find the AREA of the rectangular lot.
Area of a rectangle = Length × Width
i.e. Area of a lot = 72.2 × 50
i.e. Area of a lot = 3610 feet²
Thus, the size of the park is 3610 feet².
2. To find the amount of fencing needed, we need to find the PERIMETER of the rectangular lot.
Perimeter of rectangle = 2 × ( Length + Width )
i.e. Perimeter of the lot = 2 × ( 72.2 + 50 )
i.e. Perimeter of the lot = 2 × 122.2
i.e. Perimeter of the lot = 244.4 feet.
Thus, the amount of fencing needed for the park of the park is 244.4 feet.
