Answer:Did he ever come back?
Step-by-step explanation:
12
You want to find an equivalent ratio with 2:3. As the question already gives you 8 where 2 used to be, you need to find out what change occurred to get from 2 to 8 (a multiplication of 4). To find the missing part of the ratio, multiply 4 with 3 to get 12.
Answer:
The standard coordinates of the point are ; ( 0,0 )
Step-by-step explanation:
The standard coordinates of the point are ; ( 0,0 ) also the standard values of the means will also be ( 0, 0 )
This is because for the Positive Z-equal line, Negative Z-Equal line and Regression line to all pass through the same point indicates dependent and independent variables of the Z-score and regression lines respectively
Answer: 0.0016
Step-by-step explanation:
Given the following :
Population mean(m) = 196
Population Standard deviation (sd) = 32
Number of sample (n) = 18
Sample mean (x) = Total weight of sample / number of samples = 3928 / 18 = 218.2
Obtaining the test statistic (z) :
Z = [(x - m) / (sd/√n)]
Z = [(218.2 - 196) / (32/√18)]
Z = [(22.2 / 7.5424723)]
Z = 2.943
Hence,
P(Z > 2.94) = 1 - P(Z < 2.94)
= 1 - 0.9984
= 0.0016
