True or False

1. As the degrees of freedom increases, the probability density function of the Student’s t- distribution approaches the standard normal distribution.
2. The Central Limit Theorem states that the sample mean of a random sample is approximately normally distributed, if the random sample came from a large population with finite mean and variance and the sample size is sufficiently large.
3. If Ho is rejected at 0.05 level of significance, then Ho will also be rejected at 0.10 level of significance using the same test on the same dataset.
4. A 95% confidence interval estimate for μ given to be (15, 19) will reject the null hypothesis Ho: μ = 20 vs Ha: μ ≠ 20 at 0.05 level of significance.
5. In testing for a disease, the null hypothesis is the person is healthy while the alternative hypothesis is the person has the disease. If a healthy person is diagnosed as having the disease, a Type I error is committed.
6. If there is a negative correlation between anxiety and performance on complex tasks, then either high level of anxiety causes poor performance on complex tasks or poor performance on complex tasks causes high levels of anxiety.
7. A correlation of 0.29 indicates a weaker linear relationship than a correlation of -0.40.
8. A zero correlation between variables X and Y means that X and Y have no relationship.
9. If there is no relationship between two variables, then the correlation coefficient is 0.
10. A correlation of 0.96 for two variables X and Y implies that if X increases, there is a 96% chance that Y will also increase.
11. If the sample correlation coefficient between X and Y is positive, then the slope of the estimated regression line of Y on X will also be positive.
12. If a regression analysis is to be performed between the running time (in minutes) and heart rate (in bpm) of young adults, then the independent variable is the running time.

Please DO NOT respond to this question by copy/pasting the code provided elsewhere on the site, none of those work. Thanks. Virtual Memory Lab This lab project addresses the implementation of page-replacement algorithms in a demand-paging system. Each process in a demand-paging system has a page table that contains a list of entries. For each logical page of the process, there is an entry in the table that indicates if the page is in memory. If the page is in memory, the memory frame number that page is resident in is indicated. Also, for each page, the time at which the page has arrived in memory, the time at which it has been last referenced, and the number of times the page has been referenced since the page arrived in memory are maintained. The page table data structure is a simple array of page-table entries (PTEs). Each PTE contains five fields as defined below: struct PTE { int is_valid; int frame_number; int arrival_timestamp; int last_access_timestamp; int reference_count; } Each process in the system has a page table that is simply an array of PTEs. Each process also has a pool of frames that is allocated. The frame pool for a process is represented as an array of integers, where each Integer represents the frame number of a frame that is free and is available for use by the process. Note that in order to get the frame number in the pool, you first need to access the integer in the array. This lab project aims to exercise the various policies for page replacement. In particular, we study the following three page-replacement policies: First-In-First-Out (FIFO) Least-Recently-Used (LRU) Least-Frequently-Used (LFU) In order to implement the above policies, we need to develop corresponding functions that process page accesses for a process. That is, for each process, given its page table, a logical page number being referenced and the free frame pool of the process, the functions should determine the memory frame number for the logical page. Also, the functions should modify the page table and the free frame pool appropriately. The details of the functions with respect to the different policies are described below. You need to develop code for these functions that implement the specifications. Place the code in a file called virtual.c. You should include the oslabs.h file.

7-Eleven Malaysia Holding Berhad's annual report for the fiscal year ending 2021 is available at https://www.7eleven.com.my/financial-reports. (At least two years of comparable financial statements are required.) a) Assess 7-Eleven’s financial position for year 2020 and 2021 according to i) liquidity position, and how the liquidity position has changed over time from 2020 to 2021. (6 marks) ii) asset management position, and how its asset management efficiency has changed over time. (6 marks) iii) debt management position, and how its debt management has changed over time. (6 marks) iv) profitability ratios, and how its profitability position has changed over time. (6 marks) v) market value ratios, and how its valuation has changed over time. (6 marks) b) Calculate 7-Eleven’s ROE as well as the industry average ROE, using the DuPont equation. From this analysis, how does 7-Eleven’s financial position. (10 marks) c) Write your opinion on what you think would happen to its ratios if the company initiated cost-cutting measures that allowed it to hold lower levels of inventory and substantially decreased the cost of goods sold. No calculations are necessary. Think about which ratios would be affected by changes in these two accounts. (10 marks)

In this week’s reading, you learned about one-to-one and many-to-many relationships. While the concepts may seem beneficial, there are some drawbacks. For this discussion, you need to evaluate the pros and cons of each and make a recommendation regarding the usefulness of using these concepts in the JCC RDBMs .
