Using shifting concepts, it is found that the correct option is:
- Vertical stretch, horizontal shift left, vertical shift up.
The original function is:
- The original function was multiplied by 2, hence there was a <em>vertical stretch</em> by a factor of 2.
, hence, there was an horizontal shift left.
- 2 was added to the function, hence, there was a <em>vertical shift up.</em>

Answer:
By the Central Limit theorem, the mean of the distribution of sample means is 643.6 minutes.
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.
In this problem
The mean of the population is 643.6 minutes.
By the Central Limit theorem, the mean of the distribution of sample means is 643.6 minutes.
