Answer:

Step-by-step explanation:
The missing parameters are:
--- population
--- population mean
-- population standard deviation
Required

First, calculate the sample standard deviation




Next, calculate the sample mean 

So:

So, we have:



Calculate the z score




So, we have:

From the z table

So:

I’m not sure about the estimates but the overall answers should be correct
Answer:
m/8
Step-by-step explanation:
the equation would be 8y/8 =y and x/8= x/8. y=x/8 so you would start the line at 0 and count 8 units to the right and 1 unit up
Answer:
Step-by-step explanation: (Equation 2) = 12(-12+9y/4) - 10y = -8
-144+108y/4 - 10y = -8
-144 + 108y - 40y/4 = -8
-144 + 108y - 40y = -32
108y - 40y = -32+144
68y = 112
Y= 1.64
2-4x+9y=14
12x-10y= -8
2-14+9y = 4x
-12 + 9y = 4x ( equation 3)
(Put in equation 2)
