  1. An outbreak of Salmonella-related illness was attributed to ice cream produced at a certain factory. Scientists measured the level of Salmonella in 9 randomly sampled batches of ice cream. The levels (in MPN/g) were: 0.593 0.142 0.329 0.691 0.231 0.793 0.519 0.392 0.418. Is there evidence that the mean level of Salmonella in the ice cream is greater than 0.3 MPN/g? Use historical standard deviation of 0.3
Expert Solution
Step 1

1.

Given

The given data is as follows:

Sample size, n=9

The levels (in MPN/g) were: 0.593, 0.142, 0.329, 0.691, 0.231, 0.793, 0.519, 0.392, 0.418

Historical standard deviation is the population standard deviation, σ=0.3

The general level of significance of α=0.05 has been assumed as nothing has been mentioned in the question.
