Question:
The following results in the table are obtained from a consumer panel (n=100). Consumers were asked ‘Would you normally consume/buy this product? Yes or No?’. By using the number of the consumers rejected the product after a certain time, estimate the sensorial shelf life of frozen pasta with tomato sauce via survival analysis using the Weibull model. Use nonlinear curve fitting. Write down the shelf life equation with parameters you have found. Report the shelf life at the rejection limit of 70%.
