5 5. Vitamins To analyze the variation of vitamin supplement tablets, you randomly select and weigh 14 tablets. The results are shown below: 500.000 499.995 500.010 499.997 500.015 499.988 500.000 499.996 500.020 500.002 499.998 499.996 500.003 500.000 a. Assume this sample is taken from a normally distributed population. Construct a 90% level of confidence for the population variance and population standard deviation. b. For quality control, the population standard deviation of the tablets' weights should be less than 0.015 milligrams. Does the confidence interval you constructed for the population standard deviation suggest that it is at an acceptable level? Explain your reasoning.

a. Assume this sample is taken from a normally distributed population.
Construct a 90% level of confidence for the population variance and
population standard deviation.
b. For quality control, the population standard deviation of the tablets'
weights should be less than 0.015 milligrams. Does the confidence
interval you constructed for the population standard deviation suggest
that it is at an acceptable level? Explain your reasoning.
