I am writing a literature review for academic research. Following the topic: ARIMA model, LSTM model, GARCH model for stock market forecasting, mainly focusing on developing countries since there seem to have greater fluctuations leading to the ineffectiveness of the models. From the research published in 2021, write a literature review with citations and references. Do not use research papers published other than in 2021. Skip steps and suggestions.

A food magazine claims that 'Holy Cow' white cheddar popcorn weighs 5.7300 ounces. A random sample of 48 bags of 'Holy Cow' white cheddar popcorn weighs on average 5.4700 ounces with a standard deviation ounces. Perform an appropriate hypothesis test at the 0.0100 level of significance. Assume a normal distribution. Instructions Answers to 3 decimal places if required If a 2 tail test input the Positive Critical Value Note: The system will always mark the Null and Alternative Hypothesis Statements as incorrect (even if the student has inputted the correct answer). Consequently there are no marks for this section of the question. I left it in, as the answer given by the system is actually correct and therefore you can compare it with your own. Answer: The Null Hypothesis Statement = The Alternative Hypothesis Statement = The Critical Value = The Test Value = Is the Null Hypothesis True? 0 \text{--} Accept, 1 \text{--} Reject = Is the Claim True? 0 \text{--} Accept, 1 \text{--} Reject =

A large company employing several thousand workers in a large city in the southeastern United States would like to estimate the proportion of its employees who prefer to work from home rather than commute to its campus. The company hopes to use the information to develop a proposal to determine the best way to retain current and future employees. A pilot study of 100 randomly sampled employees found that 25 would prefer to work from home. Complete parts a and b. a. How many more employees must the company randomly sample to be able to estimate the true population of employees who prefer to work from home with a margin of error of 0.03 and a level of confidence of 90%? The company must sample 464 more employees. (Round up to the nearest whole number.) b. Suppose that after the full sample is taken, it was found that 101 employees prefer to work from home. Construct a 90% confidence interval estimate for the true population proportion of employees who prefer to work from home. (Hint: The sample size will be the total sample size required in part a, not just the additional employees.) The 90% confidence interval estimate is 0.129\text{---}0.175. (Round to three decimal places as needed. Use ascending order.)
