Answer: B. You may use the t procedure, provided your sample size is large, say, at least 30.
Step-by-step explanation: To use a T test hypothesis, the following steps is considered;
1. Add the test hypothesis when using a T test module in the experiment
2. Add the date set that contains the columns that is to be analyzed
3. Decide which kind of T test is appropriated for the data
4. If single sample is been used, the adequate parameters should be used.
The correct statement in this case is "You may use the t procedure, provided your sample size is large, say, at least 30."

Step-by-step explanation:
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
