Answer:
The standard deviation of the sampling distribution of x overbarx, denoted sigma Subscript x overbarσx, is called the standard error of the mean . The standard deviation of the sampling distribution of x overbarx, denoted sigma Subscript x overbarσx, is called the standard distribution of the sample.
Step-by-step explanation:
The standard error (SE) of a statistic is the standard deviation of its sampling distribution or an estimate of that standard deviation. It is called the standard error of the mean (SEM) if the parameter or the statistic is the mean.
Answer:
1.178
Step-by-step explanation:
(for Jamal)
5 x 2 = 10
6 x 3 = 18
7 x 2 = 14
8 x 1 = 8
10 x 1 = 10
Mean: 10 + 18 + 14 + 8 + 10 = 60/9 = 6.6
6.6 - 5 = 1.6 x 2 = 3.2
6.6 - 6 = 0.6 x 3 = 1.8
7 - 6.6 = 0.4 x 2 = 0.8
8 - 6.6 = 1.4
10 - 6.6 = 3.4
<em>Mean Absolute Deviation:</em> 3.2 + 1.8 + 0.8 + 1.4 + 3.4 = 10.6/9 = 1.178
You have to have the same base numbers
2^4x = 2^7x
now you can cancel out the 2s and set the powers equal to each other.
4x= 7x
-11x = 0
x = 0???
im not 100% sure but i think this is what you do
Answer:
Hypothesis
Step-by-step explanation:
The scientist want to test an hypothesis which can be stated has the rock on earth contain the same as the moon which can call null hypothesis and the rock on earth did not contain the same element as the moon; the alternate hypothesis and both hypothesis can be tested by using experiment.
