Question: A waste management consultant is investigating the waste generated by households. She is certain that the weights of household waste are distributed normally. She selects a random sample of 12 households and measures the weight of the waste they put in their ‘wheelie bin’ one week. The results (to the nearest kilogram) are as follows:
28 41 36 50 17 39 21 64 26 30 42 12
- Use the figures to construct a 99%confidence interval for the mean weight of waste in ‘wheelie bins’.
- Does the interval suggest that the mean weight of the contents of all ‘wheelie bins’ can be assumed to be less than 40 kg?
