Answer:
Step-by-step explanation:
Using table calculating the mean for each case
1. Entire year, sample size 12
- x = 1/12* ∑ xi, i= 1 to 12
- x = 1/12(40+42+40+38+48+50+58+62+56+46+44+44)
- x = 1/12*568 = $47.33
2. First six months, sample size 6
- x = 1/6*∑ xi, i= 1 to 6
- x = 1/6(40+42+40+38+48+50)
- x = 1/6*258 = $43
3. April through November, sample size 8
- x = 1/8*∑ xi, i= 4 to 11
- x = 1/8(38+48+50+58+62+56+46+44)
- x = 1/8*402 = $50.25
