Answer:
2.68
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(also called standard error of the mean)
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:

So

Add h and j cuz it with x
About 19.09 since, 133.65 divided by 7 is 19.092 etc. and when you round to the nearest hundredth. it is $19.09
