The law of radioactive decay is n(t) = n0e-λt, where n0 is the number of radioactive nuclei at t = 0, n(t) is the number remaining at time t, and λ is a quantity known as the decay constant. what is the dimension of λ? (t = time)

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
