Rule of thumb in basic rounding is 5 above round up, below five don’t round up.
To round to the nearest thousand, you look at the hundred place. What is the number nearest to?
71,903 Is rounded up to 72,000
^
25,368 is rounded to 25,000
^
72,000 - 25,000 = 47,000

Using the Central Limit Theorem, nothing can be stated about the shape of the sampling distribution for the sample mean, as the sample size is less than 30.
<h3>What does the Central Limit Theorem state?</h3>
It states 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 sampling distribution is also approximately normal, as long as n is at least 30.
In this problem, we have a skewed variable and n < 30, hence nothing can be stated about the shape of the sampling distribution for the sample mean.
