Answer:
The standard error for the sample mean is 0.0289.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a large sample size can be approximated to a normal distribution with mean and standard deviation
The standard deviation of the sample is also called standard error for the sample mean.
We have that:
The standard error for the sample mean is 0.0289.
Step-by-step explanation:
-2x+5<3
-2x>3-5
-2x>-2
Divide both sides by -2
x>1
Answer:
