Hi!!Could you please explain your question more?
Answer:
Step-by-step explanation:
a). Mean of the given data set = 
= 28
b). x 
32 32-28 = 4 16
28 28 - 28 = 0 0
18 18 - 28 = -10 100
40 40 - 28 = 12 144
22 22 - 28 = -6 36
= 296
c). Standard deviation = 
= 
= 7.69
d). Mean of the new set of weights = 
= 34
Since mean of the data set is more close to each data, standard deviation will be less than the deviation given in part (c).
Well I don't know if i'm answering the question, but 30 workers surveyed were satisfied with the benefits they received from the employers because 300 multiplied by .10 is 30. Hope my answer is useful.

Answer:
Pat drank 26/6 (4 1/3 or 13/3) cups of punch.
Step-by-step explanation:
Here is how I would solve this-
What is the question? How much punch did she drink in all?
What do we need to know? 11/3 + 4/6 cups of punch.
How can we make them have a common denominator? 22/6 + 4/6
Add them together! (22 + 4 = 26) so you get 26/6
Final Answer = Pat drank 26/6 (4 1/3 or 13/3) cups of punch.
Hope this helps! Good luck and let me know if this is right!
