Answer:
The vertical asymptotes are x = 2 and x = -2.
The horizontal asymptote is y = 3.
Step-by-step explanation:
Given the function
Rewrite it as follows:
This function is undefined when the denominator is equal to 0. The denominator is equal to 0 when x = 2 or x = -2, so two vertical asymptotes are x = 2 and x = -2.
The horizontal asymptote is y = 3.

Answer:
The value of the test statistic is t=1.12.
Step-by-step explanation:
This is a hypothesis test for the difference between populations means.
The claim is that the mean amount of time required to reach a customer service representative significantly differs between the two hotels.
Then, the null and alternative hypothesis are:
The sample 1, of size n1=20 has a mean of 2.65 and a standard deviation of √2.952=1.72.
The sample 2, of size n2=20 has a mean of 2.01 and a standard deviation of √2.952=1.89.
The difference between sample means is Md=0.64.
The estimated standard error of the difference between means is computed using the formula:
Then, we can calculate the t-statistic as:
