A quality assurance analyst is interested in estimating the population mean weight of cat food in boxes for a particular brand of cat food. The analyst obtains a simple random
sample of fifteen boxes and measures the weight, in grams, of the cat food
in each box. The following sample data are obtained (note these data are not the same as the other quiz
questions about cat food):
100.1
100.2
101.2
101.3
10.9
100.1
100.1
100.1
100.3
100.3
100.2
100.1
400.0
405.0
400.1
Calculate the sample standard deviation. You may wish to use Excel. Round your answer to 1 decimal place (e.g. if you get 500.55, round to 500.6).
