Answer:
a
The probability that the selected joint was judged to be defective by neither of the two inspectors is
b
The probability that the selected joint was judged to be defective by inspector B but not by inspector A is
Step-by-step explanation:
From the question we are told that
The sample size is
The number of outcome for inspector A is
The number of outcome for inspector B is
The number of joints judged defective by both inspector is
The the probability that the selected joint was judged to be defective by neither of the two inspectors is mathematically represented as
Now
substituting values
So
the probability that the selected joint was judged to be defective by inspector B but not by inspector A is mathematically represented as
Now
substituting values
So
The best answer from the options that proves that the residual plot shows that the line of best fit is appropriate for the data is: ( Statement 1 ) Yes, because the points have no clear pattern
X Given Predicted Residual value
1 3.5 4.06 -0.56
2 2.3 2.09 0.21
3 1.1 0.12 0.98
4 2.2 -1.85 4.05
5 -4.1 -3.82 -0.28
The residual value is calculated as follows using this formula: ( Given - predicted )
1) ( 3.5 - 4.06 ) = -0.56
2) ( 2.3 - 2.09 ) = 0.21
3) ( 1.1 - 0.12 ) = 0.98
4) (2.2 - (-1.85) = 4.05
5) ( -4.1 - (-3.82) = -0.28
Residual values are the difference between the given values and the predicted values in a given data set and the residual plot is used to represent these values .
attached below is the residual plot of the data set
hence we can conclude from the residual plot attached below that the line of best fit is appropriate for the data because the points have no clear pattern ( i.e. scattered )
