Answer:
CI = ( 36,6 ; 41,4 )
Step-by-step explanation:
CI = 99,9 % α = 0,1 % α = 0,001
We find z scre for α = 0,001 in z -table
z(s) = - 3,08
CI = μ₀ ± MOE where μ₀ = 39 min and MOE = z(s) * σ/√n
CI = 39 ± 3,08 * 4,8 / √37
CI = 39 ± 2,4315
CI = ( 36,6 ; 41,4 )

Answer:
C
Step-by-step explanation:
(My answer is in the picture. Hope it helps ^-^)
2/3x +12/3 =7
2/3x + 4 =7
2/3x=7-4
2/3x=3
x=3*3/2
x=3
10y + 70= 12y
12y-10y=70
2y=70
y=70/2=35
Find the closest whole number estimate for 3.8 and 6.1
The estimate for both numbers are, 4 and 6.
3.8 is rounded up to the nearest whole number, while 6.1 is rounded down to 6because the 1 after the decimal is an insignificant number (its less than 5)
