Answer:
You get paid $9 per hour
Step-by-step explanation:
The solution would be like this for this specific problem:
Given:
N = 256
Sample Mean = $35,420
Standard Deviation = $2,050
Find:
Standard Error of Mean = ?
The
formula for the standard error of the mean is:
<span>Om
= o / sqrt(N)</span>
<span>Om
= the </span>standard deviation of the sampling
distribution of the mean
where
o = standard deviation of the sampling distribution of a statistic
N
= sample size
<span>So
substituting the formula with the given:
Om = $2,050 / sqrt(256)</span>
<span>Om
= $2,050 / 16</span>
= $128.125
Therefore, the sample standard error of the mean is
$128.125.
Answer:
3.6 mph
Step-by-step explanation:
to find the average speed you need to divide your total distance by total time. Im this case you need to divide 12 by to find the average speed you need to divide your total distance by total time. Im this case you need to divide 12 by 3.25
Answer: 70 bottles of each
Step-by-step explanation:
let X be bottles of port and claret
X = 2/5
1/2 X = 1/5
180 + 30 = 210 = 3/5
210/3 = 70 = 1/5
70 x 2 = X = 140
2/5 = 140
1/5 = 70
