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
