Answer:
(B) 0.2843
Step-by-step explanation:
Let d represent the difference in proportions between Country X and Country Y for adults who first married from ages 18 to 32.
The hypotheses can be stated as
: d=0.15
: d<0.15
The test statistic can be computed with the formula
where
- p1 corresponds to the sample proportion from Country X (0.36)
- p2 corresponds to the sample proportion from Country Y (0.26)
- p indicates the pooled proportion of p1 and p2 (
)
- n1 is the sample size from Country X (60)
- n2 is the sample size from Country Y (50)
Thus,
is approximately 0.5646
The p-value for this test statistic is approximately 0.2843
The p-value indicates the likelihood that the difference in proportions between a random sample of 60 adults from Country X and a sample of 50 adults from Country Y who were first married at ages 18 to 32 is at least 0.15.
It is not possible, as there are just 2 sides, and they likely flipped it in various ways. They experienced some 'luck'.
Response:
Detailed explanation:
The length of the pool is longer than its width by 8 meters.
If we designate L as length and W as width, we can express this as:
L = 8 + W
We also know that the area amounts to 105 m squared.
Note:
Area of a Rectangle = Length x Width
Thus, 105 = (8 + W) x W

To adjust the equation, subtract 105 from both sides:

Answer:
17 calls daily
Step-by-step explanation:
500 calls ÷ 30 days = 16.6666667 calls daily
OR
≈ 17 calls per day
