Label the following 2-sample tests as: Proportions, Independent, and Dependent (matched-pairs). Determine the null and alternative hypothesis and whether the test is one-tailed or two-tailed. Then explain in detail the reasons behind your answers. You do not have to work the problems out. 1. The pre-test scores for 6 students were: 5, 5, 6, 7, 7, 8. The post-test scores for the same 6 students were: 7, 6, 7, 7, 9, 9. Is there a statistically significant difference between the two scores if we assume that the post-test scores were higher at the .01 level? 2. One group of 8 students took a pre-test, while another group of 7 students took a post-test. The following are the results: Pre-test: 5,6,4,3,4,6,6,7. Post-test: 6,6,8,7,9,8,8. Is there a difference between pre and post-test scores at the .01 level? 3. Two surveys were conducted asking participants whether they thought the morality of Americans was decaying or not. The percent of those who thought there was a decay in morality was 56% in survey 1, while the percent of those who thought there was a decay in morality was 59.5% in survey 2. Test the claim survey 2's percent was larger at the .05 level.

A researcher obtains the following sample from people who like to read comic books about how many movies they saw last month.

Sample: 5, 0, 4, 7, 3, 7, 8, 2, 9, 3.

The average number of movies people in the general population see in a month is 2.

On the basis of this sample, is the average number of movies seen by comic book fans significantly different from the general population? Use a two-tailed test with α = 0.05. Make sure you show all your steps.        (6 points)

***This is done with Java programming***

Write a well-documented (commented) program, “ISBN,” that takes a 9-digit integer as a command-line argument, computes the checksum, and prints the ISBN number.

You should use Java’s String data type to implement it. The International Standard Book Number (ISBN) is a 10-digit code that uniquely specifies a book. The rightmost digit is a checksum digit that can be uniquely determined from the other 9 digits, from the condition that d1 + 2d2 +3d3 + ... + 10d10 must be a multiple of 11 (here di denotes the ith digit from the right).

The checksum digit d1 can be any value from 0 to 10. The ISBN convention is to use the character X to denote 10. The checksum digit corresponding to 032149805 is 4 since 4 is the only value of x between 0 and 10 (both inclusive), for which 10·0 + 9·3 + 8·2 + 7·1 + 6·4 + 5·9 +4·8 +3·0 + 2·5 + 1·x is a multiple of 11.

Sample runs would be as follows.

>java ISBN 013376940
The ISBN number would be 0133769402

>java ISBN 013380780
The ISBN number would be 0133807800

Periodic Inventory by Three Methods

Dymac Appliances uses the periodic inventory system. Details regarding the inventory of appliances at January 1, purchases invoices during the next 12 months, and the inventory count at December 31 are summarized as follows:

Required:

1. Determine the cost of the inventory on December 31 by the first-in, first-out method.

If the inventory of a particular model comprises one entire purchase plus a portion of another purchase acquired at a different unit cost, use a separate line for each purchase. If units are in inventory at two different costs, enter the units PURCHASED MOST RECENTLY first.

2. Determine the cost of the inventory on December 31 by the last-in, first-out method.

If the inventory of a particular model comprises one entire purchase plus a portion of another purchase acquired at a different unit cost, use a separate line for each purchase. If units are in inventory at two different costs, enter the OLDEST units first.

3. Determine the cost of the inventory on December 31 by the weighted average cost method.

4.   would be preferred for income tax purposes in periods of rising prices.
