i) a 95% confidence for weight variable = (2897.023, 3061.804586)
Interpretation :
The 95%confidence interval (2897.023, 3061.804586) has a 0.95 probability of containing the population mean of weight variable.
ii) a 95% confidence for accleration variable = (15.24701284, 15.79239602)
Interpretation :
The 95%confidence interval (15.24701284, 15.79239602) has a 0.95 probability of containing the population mean of accleration variable.
iii) a 95% confidence for MPG variable = (22.74668427,24.28246145)
Interpretation :
The 95%confidence interval (22.74668427,24.28246145) has a 0.95 probability of containing the population mean of MPG variable.
iv) a 95% confidence for Horsepower variable = (101.3113381, 108.8536619)
Interpretation :
The 95%confidence interval (101.3113381, 108.8536619) has a 0.95 probability of containing the population mean of Horsepower variable.
