Find the 95% cоnfidence intervаl fоr the stаndаrd deviatiоn of the weight of ten-gallon drums of motor oil:if a sample size of 20 of these drums had a variance of 3.2 ounces.For question 17, give the table value you are going to use in your set up for Chi-squared right. For question 18, give the table value you are going to use in your set up for Chi-squared left.For question 19, give the highest value of your calculated standard deviation of the 95% confidence interval. (Hint/reminder: Chi-squared tables use degrees of freedom)

Parasympathetic preganglionic neurons exit the central nervous system at the __1__. Parasympathetic preganglionic neurons synapse with parasympathetic postganglionic neurons in __2__. The parasympathetic preganglionic neurons will release __3__, which binds to __4__ on the postganglionic soma and dendrites. The release of this neurotransmitter classifies the neuron as a(n) __5__. The parasympathetic postganglionic neuron releases __6__ , which will cause a(n) __7__in digestion.
