3. For the Price variable, test the hypothesis of µ being
different than 11,500 at the 5% level of significance:
(a) (10 pts) State your null and alternative hypotheses.
(b) (10 pts) Find the relevant p-value and write it down.
(c) (10 pts) What do you conclude, based on your findings?
(a) The hypothesis being tested is:
H0: µ = 11500
Ha: µ ≠ 11500
(b) The p-value is 0.0000.
11,500.0000 | hypothesized value |
10,117.1100 | mean Price |
3,069.4837 | std. dev. |
306.9484 | std. error |
100 | n |
99 | df |
-4.505 | t |
1.82E-05 | p-value (two-tailed) |
(c) Since the p-value (0.0000) is less than the significance level (0.05), we can reject the null hypothesis.
Therefore, we can conclude that µ ≠ 11500.

Using Doubly Linked List, and Sorting methods: (In Java) (please attach your output with the answer) (Please answer if it is correct and working) (Have been getting many wrong and spam answers lately) Introduction: In this project, we use the same file structure of Artist and Art to extend the concepts of array and linked list and have them applied to sorting. The input files of p1arts.txt and p1artists.txt have been slightly modified. They are named p7arts.txt and p7artists.txt. Assignments:...
Using Merge Sort: (In Java) (Please screenshot or copy your output file in the answer) In this project, we combine the concepts of Recursion and Merge Sorting. Please note that the focus of this project is on Merging and don't forget the following constraint: Programming Steps: 1) Create a class called Art that implements Comparable interface. 2) Read part of the file and use Merge Sort to sort the array of Art and then write them to a file. 3)...
