At the end of the semester the lecturer runs a regression using the student's final grade as the dependent variable and a male dummy (equals one if the student is male and equals zero otherwise) as the sole explanatory variable. If the estimated intercept is 64 and the estimated coefficient on the male dummy is 0 then what is the estimated mean mark for males in this course?
The following data table shows the historical data for the first semester 2020, of the amount of sales of the company "IRC", which sells sneakers. Utilizing multiple lineal regression (as shown on the image), find an equation that estimates the number of sneakers sold by the company, based on advertising and revenue. Also, determine the standard error of estimation, the coefficient of determination, and the correlation coefficient. Write down what was the quantity in thousands sold in July if the amount of ads was 8 and the income for each unit was $135
Which croc? The ranges inhabited by the Indian gharialcrocodile and the Australian saltwater crocodile overlapin Bangladesh. Suppose a very large crocodile skeleton isfound there, and we wish to determine the species of theanimal.
