Step-by-step explanation:
40% own neither, it means 100% - 40% = 60% own either a dog or a cat.
Since 45% own a dog, 60% - 45% = 15% own a cat but not a dog.
Since 25% own a cat and 15% own only a cat, 25% - 15% = 10% own a dog and a cat.
Now, 10% out of 45% own both pets, 45% - 10% = 35% own only a dog.
<u>All the numbers reflected in the attached Venn diagram:</u>
- 35% - dog
- 10% - both
- 15% - cat
- 40% - neither
The absolute value equation representing the minimum and maximum time taken to travel a 10 mile distance is 0.5 ≤ t ≤ 2
<u>Given the Parameters</u> :
- Minimum distance = 2.5 miles
- Maximum distance = 10 miles
<u>Recall</u> :
- Time taken = distance / speed
<u>Minimum time taken</u> :
<u>Maximum time taken</u> :
Therefore, the absolute value equation for the time taken can be expressed as 0.5 ≤ t ≤ 2

Answer: The margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.
Step-by-step explanation:
Since we have given that
Sample size = 400
Mean = $357.75
Standard deviation = $37.89
At 95% confidence level, z = 1.96
We first find the margin of error.
Margin of error is given by
95% confidence interval would be
Hence, the margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.
