Please help me out by giving me detailed answers with formulas. So I can understand fully Thank you very much A study is conducted to examine the influence of ‘screen time’ on student performance on Statistics exams. A class of 12 students is observed over a period of time, with the independent variable being the average amount of time per day each student spends on TV/internet, and the dependent variable being their subsequent Statistics exam score, in %. The data...
My last question has gone hours without being answered, so I
am submitting these again. Anyone who could help with these 10
questions would be MASSIVELY appreciated. Thank you!!

In the United States, tire tread depth is measured in 32nds of an inch. Car tires typically start out with 10/32 to 11/32 of an inch of tread depth. In most states, a tire is legally worn out when its tread depth reaches 2/32 of an inch. A random sample of four tires provides the following data on mileage and tread depth: Mileage (10,000 miles) Tread Depth (32nds of an inch) Tire You vwill use the sample data to find...
please explain how to get answers! i rate! :) thank you
An accountant wishes to predict direct labor cost() on the basis of the batch size (x) of a product produced in a job shop. Data for 12 production runs are given in the table below, along with the Excel output from fitting a least squares regression line to the data.

making sure i did them right.
please answer all 4.
From theoretical considerations, it is suspected that the rate of flow from a fire hose is proportional to some power of the pressure at the nozzle. Do the following data confirm this observation? Get the least-squares values for the exponent and the proportionality factor Q1.
