A fаctоry is testing twо different pаckаging machines. Fоr each machine a random sample of 10 boxes is chosen and the time, in seconds, that it takes to pack the box is measured. The data is recorded in the table below. Machine 1 Machine 2 41.9 42.3 42.9 42.1 41.8 40.8 41.5 42.9 42.7 43.0 42.8 42.9 41.4 43.4 41.2 42.2 42.7 42.6 41.9 42.0 Where rounding is necessary, round to two decimal places. 1. What is the point estimate of the mean packing time for Machine 1? [mean1] 2. What is the point estimate of the mean packing time for Machine 2? [mean2] 3. Find the 95% confidence interval for the difference in mean packing times for Machine 1 and Machine 2. Assume that the conditions to compute the confidence interval are met. We are 95% confident that the difference in the mean packing times for Machine 1 and Machine 2 is between [lower] seconds and [upper] seconds. 4. Based on the confidence interval, can you say that one of the machines has a lower mean packing time? [Yes] based on the confidence interval, we [can] say that [machine] has a lower mean packing time because [because].
