Answer with explanation:</h2>
By considering the given information, we have
Null hypothesis : 
Alternative hypothesis : 
Since the alternative hypothesis is two-tailed , so the test is a two-tailed test.
Given : Sample size : n= 20, since sample size is less than 30 so the test applied is a t-test.
; 
Test statistic : 
i.e. 
Degree of freedom : n-1 = 20-1=19
Significance level = 0.01
For two tailed, Significance level 
By using the t-distribution table, the critical value of t =
Since , the observed t-value (7.25) is greater than the critical value (2.861) .
So we reject the null hypothesis, it means we have enough evidence to support the alternative hypothesis.
We conclude that there is some significance difference between the mean score for sober women and 35.0.

Answer: vertical line.
Step-by-step explanation:
Ok we can define a function f(x) as "something" that maps a given input (we usually call the input "x") into a given output (we usually call the output "y")
We have one rule for functions, each input can be mapped into only one output.
So if for example, for a given value x = A.
f(A) = B
and
f(A) = C
This is mapping the input A into two different outputs, then this is not a function.
Now to the question.
If we have a vertical line (parallel to the y-axis)
This line will have only one value of x associated with it, but all the values of y.
This means that this maps one value of the input into infinite outputs, then this can not be a function.
