- Please help me with this question if you know how to use the R software. I am very confused and my teacher tells me to type ?longley in the software but I still struggle to understand this question and answer it properly. Any help would be tremendously appreciatedSuppose we have a dataset containing 50 rows, one row for each state. The population of each state, measuredin millions of people, is a variable in that data set. Below is a histogram for the population data. I have attached the bar graph- I am havinng trouble discerning which axis is the state and which axid is the population count? theres only 14 on one axis and 44 on the other. Doesn't make sense for a state to have a zero population. Can you tell which is which? a) What proportion of states have a population between 6 and 10 million? what is the mean population? what is the median population?The following table was generated from the sample data of 1010 junior high students regarding the average number of hours they are unsupervised per night, the average number of hours they play video games per night, and their final grades in their math class. The dependent variable is the final grade, the first independent variable (x1x1) is the number of hours unsupervised each night, and the second independent variable (x2x2) is the number of hours of video games each night.

A researcher was investigating variables that might be associated with the academic performance of high school students. The data included the average Math SAS score of all high school seniors in the city that took the exam (labeled as the variable SAT-M), the average number of dollars per pupil spent on education by the city (labeled as the variable $Per Pupil), and the percentage of high school seniors in the city that took the exam (labeled as the variable %Taking). As part of the researcher's investigation, he ran the following multiple linear regression model as SAT-M=Beta0 + Beta1($Per Pupil) + Beta2(%Taking). This model was fit to the data using the method of least-squares, results shown inside of table within photo. Question: What's the 95% confidence interval for Beta1, (coefficient of variable $PerPupil). Then determine the interpretation for Beta2 (coefficient of %Taking variable).The residents of a housing development for senior citizens have completed a survey whereon they indicated how physically active they are and how many visitors they receive each week.
