Answer:
Mean= 5.70
Standard deviation= 0.132
Step-by-step explanation:
For the distribution of sample mean:
Mean of the sampling distrubution = \mu = 5.70
Standard deviation of the sampling distrubution = sigma/sqrt{n} = 1.7201 /sqrt{170} = 0.132
I think you divide 18.96 by 3 to get the amount for one pound cost then go pound for pound there
Days attended = 174
% attendance = 174/182 * 100 = 95.60%
18 is an even number because if you divide 18 ÷ 2 = 9 it guves you an odd number
