Answer:
Confidence Interval in 95% confidence level for the quality rating is (6.06,7.46)
Step-by-step explanation:
Confidence Interval can be calculated using the formula M±ME where
- M is the mean of the sample
- ME is the margin of error in a given confidence level
Using the sample obtained from 50 business travelers we get
- Mean of the sample is 6.76
- standard deviation of the sample is 2.526
Margin of error (ME) around the mean using the formula
ME= where
- z is the corresponding statistic in 95% confidence level (1.96)
- s is the standard deviation of the sample (2.526)
- N is the sample size (50)
Using the numbers in the formula we get:
ME= ≈ 0.70
Then the confidence interval becomes 6.76±0.70
Hi there! The answer is y = 1/6x + 1/2
To find the inverse function x and y need to switch places.
Now rewrite the equation, until it will be in standard form (slope-intercept form) again.
Add 3.
Switch sides.
Divide both sides by 6.
Hence, the answer is y = 1/6x + 1/2.
~ Hope this helps you!
