Step-by-step explanation:
Step 1
Subtract the mean from your score. For example, if you scored 33 and the mean is 24, you would get a difference of 9.
Step 2
Divide the difference found in Step 1 by the standard deviation of the data to find the z-score, which is the number of standard deviations away from the mean that your score is. For example, if the standard deviation was 4.5, you would have a z-score of 2.
Step 3
Convert the z-score to a percentile using a z-score chart or converter available online (see Resources section). When converting, be sure to use a one-sided test. For example, a z-score of 2 would be in the 98th percentile.
Answer:
Butch should be awarded with 9,2 points
Step-by-step explanation:
Roofy gets 9 points out of 10 missing only a pipe, that means that each pipe is awarded with 1 point
Ralph gets 7 points out of 10 missing one pipe ( 1 point ) and 2 points missing a beam
So points are awarded as follows
1 point by pipe then 4 points for 4 pipes
2 points by beam then 4 points for 2 beams
We just have 2 points to award 10 jumps then each jump is awarded by 0,2 points
Finally as Butch missed 4 jumps, Butch should be awarded with 9,2 points
-1, -35.
When you multiply two negative numbers, you get a positive result.
