Answer:
Step-by-step explanation:
In finding this value you average lower and upper bound
(0.6+0.82)/2 = 0.71
=0.71 estimated
margin of error = distance from estimate point lower/ upper bound
This interval will be twice margin error
(0.82-0.6)/2 = 0.11
How far is 0.82 from 0.71 ??
=0.11=11%
Answer: (1) mean = 9.46; standard deviation = 3.74
Step-by-step explanation:
Rain : sunny : overcast
7:11:3
7x + 11x + 3x = 366
21x = 366
x = 366/21
x = 17.43
7(17.43) = 122.01 days rain
11(17.43) = 191.73 days sunny
3(17.43) = 52.29 days overcast
