Explanation:

- How many months is 23 weeks?

Each month has at least 4 weeks, with some months having an extra day or two.
It's given to find how many months see there in 24 weeks. For this, we need to divide the given number of weeks (23) by the number of weeks in 1 month (4).
So,

We can see that 23 weeks is <u>5.75 months which is approximately 6 months. </u>
__________________
If you want a more standard value then we can calculate weeks in 1 months as 4.345. Then, we must divide 23 weeks by 4.345.

Now, we'll get the answer as <u>5.293 months</u>.

You can write the answer in either form. Your answer can be rounded of to 6 months in the 1st explanation or it can be written as 5 months if you followed the 2nd explanation. The given weeks is 23, an odd number..so it's hard to decide the correct number of months.
this question is incomplete but I have added The Answer options to your question
a) He does not have a hypothesis.
b) He only has one group. He has not established a comparison
c) He has not measured an outcome.
d) The groups were not equal to begin with.
Answer:
b) He only has one group. He has not established a comparison
Explanation:
A randomized controlled experiment can be defined as an experiment that has two groups which it randomly assigns participants to.
These two groups are:
1.) the experimental group and
2.) The controlled group on whom the study is being performed.
Now Alberti does not have any of these groups we have listed. He performed the testing on the same people before they consumed alcohol and after they consumed alcohol. Therefore this study was not comparative in nature.
