A researcher working for an insurance company that sells life insurance would like to use regression analysis to predict life expectancy of his clients. He knows that there are several factors that contribute to life expectancy: some are genetic, some are related to life style, some are related to biological factors, and some are related to environment (access to health care, cleanliness of air, etc.) . He selects these candidate variables to develop his regression equation: gender, number of cigarettes smoked per day, cholesterol level, systolic blood pressure, and height-to-weight index: (actual weight / appropriate weight given gender, build, and height) * 100. Use the datasheet life expectancy in datasetsRM.xls to develop a regression equation to predict how long a person should live (for gender: 0=female, 1=male): 1. First, plot each non-categorical predictor variable against the dependent variable (age of death) and examine the plot to see if the relationship is linear. What’s your assessment? 2. Perform a multiple regression analysis and write up the results of your regression analysis in APA style. 3. For a male who does not smoke cigarettes at all, has a systolic blood pressure of 130, a height-to-weight index of 110, and a cholesterol level of 200, what is his life expectancy?

In our sample of 42 students, we are interested in whether the amount of money students think a first date should cost is different based on whether they are in a romantic relationship or not. The mean amount stated by the 21 students in a relationship was $58.81, with a standard deviation of $47.17, while the 21 students not in a relationship thought first dates should cost a mean of $48.10 with a standard deviation of $24.16. State the null and alternative hypotheses, conduct the appropriate type of t test, and write a conclusion interpreting your findings.

What is the result of the following statement?
not 1 or 0 and 1 or 3 and 4 or 5 and 6 or 7 and 8 and 9
It is python logical operator (not, and, or)
I know the result is 4 by running the code, but I don't understand the logic behind it, can you explain it step by step? e.g. How to eliminate those numbers in each step to get the result.

1. Due to the COVID-19 pandemic, and the stay at home order handed out by the Governor and the President we have had to use MIS more. Tools like Zoom have become widely popular and have seen increased users. However, they have also had some challenges. What are some of the challenges that Zoom has faced in the last few weeks? How would you recommend solving them?
2. Companies like Microsoft, Amazon AWS and Google have built their platform for situations like what we are experiencing. How has cloud computing evolved over the years to allow us some form of continuity? Do you believe there will be a rise in companies moving to the cloud and will there be new entrants to the cloud landscape with companies offering Saas? What are some examples of SaaS?

It is about C++linked list code. my assignment is making 1 function, in below circumstance,(some functions are suggested for easier procedure of making function.)
void remove_list(struct linked_list* list) //*This is the function to make and below is the explanation that should be written in given code.
"This function removes the list. When the list is removed, all the memory should be released to operating system (OS) so that OS lets other computer programs use this. While deleting the list, every node should be freed separately; free(list) will not remove every node in the list. To check whether the nodes are removed perfectly, for every deletion of a node, this function should print message “The node with value n (corresponding value) is deleted!” Also, if the whole list is deleted, this function should print message “The list is completely deleted: n nodes are deleted”."
