Answer: 3. 2
Step-by-step explanation:
Given the data:
3.12 2.45 4.0 3.76 3.54 2.78 3.39 3.21 1.98 3.43 3.98 2.77
Point estimate of population mean :
Σx / N
(3.12 + 2.45 + 4.0 + 3.76+ 3.54 + 2.78 + 3.39 + 3.21 + 1.98 + 3.43 + 3.98 + 2.77)
= 38.41 / 12
= 3.2008
Answer:
Step-by-step explanation:
R= -4
a= -3
using ∑n = a(1-rⁿ)/1-r
∑n:10 = -3(1-(-4)^10)/ 1-(-4)
= -3(1-1,048,576)/1+4
= -3(-1048575)/5
= 3,145,725/ 5
= 629,145
Answer:19.8
Step-by-step explanation: if you look at the lines it describes the length of the area it’s on. Since there is 4 lines on right side it would be 9.9+9.9 which would give you and answer of 19.8 so CH=19.8
