Answer:
No. The margin of error only includes sampling variability.
Step-by-step explanation:
The margin of error would be considered for the sampling error
In the case when some adults does not have telephones so it is called as error selection bias this is not a sampling error
The selection bias, unresponse bias and the response would be the examples of an error but it is not a sampling errors
So there is no margin of error as it only involved the variability in the sampling
Answer:
180 miles
Step-by-step explanation:
150/2.5 is 60; 60*3 is 180
Answer: X=44
Step-by-step explanation:
X + 6x = 308
Combine like terms
7x = 308
Divide both sides by 7
X = 44
They missed 44
The original number is degree, minutes and seconds.
There are 60 minutes in an hour and 3600 seconds in an hour.
Divide minutes by 60 and divide seconds by 3600, then add to the degrees:
15 / 60 = 0.25
66 / 3600 = 0.01833
Total degrees: 32 + 0.25 + 0.01833 = 32.2683
Rounded to the nearest 100th = 32.27 degrees.
Answer:
Step-by-step explanation:
Let x be a random variable representing the number of registered voters in the congressional district. This is a binomial distribution since the outcomes are two ways. It is either a randomly selected registered voter is a conservative or not. The success would be that a randomly selected voter is a conservative. The probability of success, p = 60/100 = 0.6
The probability of failure, q would be 1 - p = 1 - 0.6 = 0.4
Given n = 10, we want to determine P(x = 4)
From the binomial distribution calculator,
P(x = 4) = 0.11
