Answer: A) 0.016
Step-by-step explanation:
The standard error is also known as the standard deviation of sampling distribution.
Formula : 
Given : The proportion of respondents approve the job that President Barack Obama was doing handling the economy : 
Sample size : n= 1000
Then, the standard error (SE) of 
is
Hence, the standard error (SE) of is 0.016 .
Answer:
The score of 271.2 on a test for which xbar = 240 and s = 24 has a higher relative position than a score of 63.6 on a test for which xbar = 60 and s = 6.
Step-by-step explanation:
Standardized score, z = (x - xbar)/s
xbar = mean, s = standard deviation.
For the first test, x = 271.2, xbar = 240, s = 24
z = (271.2 - 240)/24 = 1.3
For the second test, x = 63.6, xbar = 60, s = 6
z = (63.6 - 60)/6 = 0.6
The standardized score for the first test is more than double of the second test, hence, the score from the first test has the higher relative position.
Hope this Helps!!!
Answer:
4.4
Step-by-step explanation:
Data set = 79, 93, 92, 86, 90
Xmean = (79 + 93 + 92 + 86 + 90)/5
= 440/5
Xmean = 88
MAD =
(79 - 88) + (93 - 88) + ( 92 - 88) + ( 86 - 88) + ( 90 - 88)/ 5
=
(9) + (5) + (4) + (2) + (2)/ 5
=
22/5
Mean Absolute Deviation = 4.4
