Step-by-step explanation:
Given
---- proportion that cursed their computer
Required
Odds against the selected
Using the complement formula, the proportion that the selected has not cursed at their computer is:
So, the odds against the selected is:
Divide by 10%
Answer:
n = 5/22
Step-by-step explanation:
That's a final solution.
Given :
Positive integers 3, 4, 5, 6, 6, 7, and x are all equal.
To Find :
The mean, median, and unique mode are all equal , find x.
Solution :
Median is the middle number in sorted list.
So, median = 6
Also, mode is the number with highest frequency.
mode = 6
So,
mean = mode = median
Hence, this is the required solution.
Answer:
The 99 percent confidence interval for the proportion of all employees at the company who own an electric car is (0.0104, 0.0496).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
In a random sample of 500 employees, 15 reported owning an electric car.
This means that
99% confidence level
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 99 percent confidence interval for the proportion of all employees at the company who own an electric car is (0.0104, 0.0496).
