A.

what is the critical t-stat? Remember to use alpha = 0.05 two-tailed.

B.

 so, is there a difference between how much the dogs will bark for these two different artists? 
Group of answer choices
No, p <.05
yes, p >.05
No, p > 0.05
yes, p <.05
 
c.

Finally, construct an 80% interval around the mean difference.

D.

What is the upper bound of that interval?

### Comparing Canine Response to Music: A Statistical Investigation

A very silly person trains their dogs to bark anytime they hear an Olivia Rodrigo song or a Juice WRLD song. Using the data below, conduct a repeated-measures t-test with an alpha level of 0.05 (two-tailed) to determine if the dogs bark more often at Ms. Rodrigo's music compared to Mr. WRLD's. 

#### Barking Response Data

| Dog               | Olivia Rodrigo Songs | Juice WRLD Songs |
|------------------ |----------------------|------------------|
| Jimmy Chew        | 15                   | 11               |
| Lil' Bow Wow      | 10                   | 11               |
| Notorious D.O.G.  | 11                   | 7                |
| Bark Twain        | 9                    | 8                |
| Sir Licks-a-lot   | 10                   | 9                |

Be sure to conduct the test as Olivia Rodrigo-minus-Juice WRLD, so that a positive value means the dogs barked more often for Rodrigo.

### Explanation 
To interpret the data correctly, use the following steps for a repeated-measures t-test:
1. **Difference Calculation:** Calculate the difference in barking frequency for each dog between Olivia Rodrigo songs and Juice WRLD songs.
2. **Mean Difference:** Compute the mean of these differences.
3. **Variance:** Calculate the variance of the differences.
4. **Standard Deviation:** Determine the standard deviation of the differences.
5. **t-Statistic:** Compute the t-statistic using the formula for the repeated-measures t-test.
6. **Critical t-value:** Compare the calculated t-statistic against the critical value for a t-distribution with the appropriate degrees of freedom.

Conduct this analysis to determine if the observed differences in barking frequencies are statistically significant, thereby indicating whether dogs bark more for Olivia Rodrigo or Juice WRLD songs.
