Step-by-step explanation:
The predicted useful life of a brand A cutting tool when the speed is 45 meters per minute is 1.2 to 5.5 hours.
The predicted useful life of a brand B cutting tool when the speed is 45 meters per minute is 3.4 to 5.4 hours.
The prediction interval for brand A is larger than the prediction interval for brand B because the estimated standard error of y^ is different for the two intervals.
The prediction intervals are both larger than the corresponding confidence intervals.
The standard error for the estimated mean value of y is smaller than the standard error for the predicted value of y.
The predicted useful life of a brand A cutting tool that is operated at 100 meters per minute is -0.59 hours
The actual predicted useful life of a brand A cutting tool when the speed is 100 meters per minute is 0.0 to 2.3 hours.
Answer:
Option C is correct ,14.2%
Step-by-step explanation:
In order to determine the effective tax rate of a taxpayer with taxable income of $52,000,the starting point to determine how much in taxes the taxpayer pays as shown below:
First tax bracket=$9,525*10%=$952.5
Second tax bracket=$952.50+(12%*($38700-$9,525))
=$952.50+$3501
Third tax bracket(where the taxpayer belongs)=4453.5
+(22%*($52,000-$38,700))
third tax bracket tax=4453.5+$2926
=$7379.5
Since the total tax payable of $7379.5 is now computed,
effective tax rate=tax paid/taxable income=7379.5/52000
=14.2%
