I assume that the numbers are: 4,4,6,1,5,2,6
If so, then the MAD is 1.43
To find the MAD, you first find the mean of the list. It is 4.
Then find the absolute difference of each number from the mean.
Those values are: 0,0,2,3,1,2,2
Now find the mean of those numbers and you have about: 1.43
Answer:
yes
Step-by-step explanation:
Answer: One sample z test for means
Step-by-step explanation:
From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
The probability value would be determined from the normal distribution table.
Therefore, the hypothesis test that should be used is
One sample z test for means
For this case what we should do is observe the figure.
We note that the side opposite to vertex B is the AC side.
From here, we can see that the length of the AC segment is given by:
AC = 4
Therefore, the measurement on the side opposite to vertex B is equal to 4 units.
Answer:
The length of the side opposite B measures 4 units
