Answer:
x > - 2
x ∈ ( - 2 ; + oo)
Step-by-step explanation:
- 5x < 10 | *(-)
5x > - 10 | : 2
x > - 2
x ∈ ( - 2 ; + oo)
Answer:
The mean of the sampling distribution of the sample proportions is 0.82 and the standard deviation is 0.0256.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For proportions, the mean is
and the standard deviation is 
In this problem, we have that:
.
So


The mean of the sampling distribution of the sample proportions is 0.82 and the standard deviation is 0.0256.
The best answer between the two choices would be the second option B) FALSE because the owner doesn't have to use his ''best'' judgement to figure out costs and expenses when it comes to sales.
