Answer:
1 is true , 2 is false
Step-by-step explanation:
for equation 2
-2x<8
-2x=8
then we divide both side by coefficient of x which is -2
-2x/-2=8/-2
we will be left with
x= 8/-2
x=-4 which shows that x<-4 and it differs from the second inequality

Answer:

Step-by-step explanation:
a. Given p=0.15.
-The mean of a sampling proportion of n=5000 is calculated as:

-The standard deviation is calculated using the formula:

Hence, the sample mean is μ=750 and standard deviation is σ=0.0050
b. Given that p=0.15 and n=1000
#The mean of a sampling proportion of n=1000 is calculated as:

#-The standard deviation is calculated as follows:

Hence, the sample mean is μ=150 and standard deviation is σ=0.0113
c. For p=0.15 and n=500
#The mean is calculated as follows:

#The standard deviation of the sample proportion is calculated as:

Hence, the sample mean is μ=75 and standard deviation is σ=0.0160
