By the Pythagorean theorem,
and
Answer:
Method A.
Step-by-step explanation:
For solving this question we need to find out the z-scores for both methods,
Since, the z-score formula is,
Where, is mean,
is standard deviation,
Given,
For method A,
Thus, the z score for 34 is,
While, for method B,
Thus, the z score for 34 is,
,
Since,
Hence, method A is preferred if the procedure must be completed within 34 minutes.
Answer:
4.1 shirts
Step-by-step explanation:
Mean can be found by adding all data points and dividing that by the total amount of data points.
There are 12 students selling shirt, which gives you 12 data points.
So (3+4+8+5+2+5+0+5+3+4+3+7)/12 = 4.083...
Which rounds to 4.1 shirts
