Step-by-step explanation:
here's the solution: -
Average time taken by sarah :
=》
=》
=》
average time taken by sarah = 70.9 seconds
now,
average time taken by katie :
=》
=》
=》
average time taken by katie = 78.9 seconds
so, sarah is more efficient (faster) than katie.
i agree with sarah.
cuz, she took less time than katie.
4/105 In total there are 2+4+1+8=15 The probability of taking a blue is number of blue divided by number of total, so that would be 4/15. Since, it is not replaced, we can now say that there are 1 less marbles in the bag (since we took out a blue). Now probability of getting a green marble is:2/14=1/7
Answer:
The correct option is;
C. She should go back and remeasure all of her specimens again to find the error. If she can't do this, she should eliminate the outlier from the analysis, because this is an error in recording
Step-by-step explanation:
In order to minimize error in measurement, some valuable steps includes;
1) Perform a double check on all measurements to ensure that the measurements recorded are accurate
2) Ensure proper training before taking measurements
3) Measurements should only be taken under controlled conditions
4) Separate the entire population into smaller groups for proper recording
5) Have a second observer double check the records
