Answer:
8,953
Step-by-step explanation:
line up 7,909 and 1,044 like this :
7,909
+ 1,044
then add everything
2 thousand 10s
Width = 5 ft
A=wl
10 = wl
24 inches = 2 ft
10 =
20
Mean= 5.70
Standard deviation= 0.132
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
