I
am trying to run a regression in R with a continuous dependent
variable and a binary independent variable? The binary one refers
to whether a person received treatment or not. how do I interpret
the regression outputs since I dont get results based 0 or 1 buf
the whole variable?

I have to do a simple linear regression project. The dependent
variable that I chose is international tourist receipts (US$
billions) and the independent variable I chose is International
tourist arrivals in (billions). Did I set up my variables
correctly? I am using data from the World Bank. The main trouble I
am having is why testing the correlation between these two
variables is important and need some ideas on answering the few
questions in the introduction of the essay,...
1. If my independent variable is height and my dependent
variable is weight, am I most likely looking at “differences” or “a
relationship”? Please explain why.
2. What is the difference between descriptive and inferential
statistics? Obviously only a crude (but accurate) answer is
necessary.
3. What is the scale of measurement for the variable “year of
birth”?

I am trying to find an
appropriate statistical test to run for a research study using
someone else's gathered data (so that no IRB process is needed). In
their data they present:
Likelihood of Falling
Asleep:
Never 17
Seldom 22
Moderate 15
High 12
Use of napping during
duty:
Never 27
Rarely 19
Sometimes 16
Often 4
Both of these seem to
be independent variables, but is there a way to show a relationship
(or lack thereof) without a dependent...

I am trying to implement a search function for a binary search
tree.
I am trying to get the output to print each element preceding
the the target of the search. For example, in the code when I
search for 19, the output should be "5-8-9-18-20-19"
Please only modify the search function and also please walk me
through what I did wrong. I am trying to figure this out.
Here is my code:
#include<iostream>
using namespace std;
class node

If a dependent variable is binary, is it optimal to use linear
regression or logistic regression? Explain your answer and include
the theoretical and practical concerns associated with each
regression model. Provide a business-related example to illustrate
your ideas.
