You supposed to estimate the optimal size of a chip based on previous data. For the previous data a large number of A = 4mm2 chips from a production run was examined and the
following data was found for the number of (fatal) defects per chip: Number of defects per die: 0 1 2 3 4 5 6 7 8 9 10 11 12    Die count: 187 45 31 17 23 12 12 5 2 0 1 0 0
a)Calculate mean and standard deviation 6 points Calculate the mean number of defects per die λ and the standard deviation σλ of the number of defects per die.

The mean salt content of a certain type of potato chip is supposed to be 2.0 mg. From each batch produced, the inspector takes an SRS of 50 bags, notes there are no outliers, and measures the salt content and gets a mean of 2.05 mg with a standard deviation 0.1. Construct and interpret a 95% confidence interval for the mean salt content of all such bags. Is there a problem with the potato chip manufacturing? (6 points) After calculating...

The number of defects in 12 different production runs were 2, 5, 10, 0, 5, 3, 4, 3, 2, 2, 0 and 0. This data can be summarized in a frequency distribution as follows a. The values that occur in the set in increasing order are 0, 2, 3, 4, 5 and 10. b. The frequency of 0 is 3 since it occurs 3 times in the set. The frequency of 2 is 3 since it occurs 3 times in...
