Answer:
Test statistic = - 2.29
Pvalue = 0.0110
Step-by-step explanation:
The hypothesis :
H0 : p = 0.3
H1 : p < 0.3
Test statistic :
z=pˆ−p/√p(1−p)/n
pˆ = 0.2
Z = (0.20 - 0.30) / √(0.30(1 - 0.30) / 110
Z = - 0.1 / √0.0019090
Z = - 0.1 / 0.0436931
Z = - 2.29
Test statistic = -2.29
The Pvalue :
P(Z < -2.29) = 0.0110
Answer:
Step-by-step explanation:
-3x - 5 = 16
add 5 to both sides of the equation
-3x = 21
divide both sides by -3
x = -7
---------------------
-4(y - 2) = 12
distribute the -4 to everything in the parentheses
-4y + 8 = 12
subtract 8 from both sides of the equation
-4y = 4
divide both sides of the equation by -4
y = -1
I Believe that the correct answer is option C) 401 r
8,441 ÷ 21 = 401.952380952
