Over the past several months, an adult patient has been treated for severe muscle spasms. This condition is associated with a low average total calcium level. Recently, a random sample of \( 10 \) of the patient's total calcium tests (measured in \( mg / dL \) ) had mean \( \overline { x } = 9.95 \) and standard deviation \( s = 1.02 \) . You may assume that the total calcium level in the patient's blood has an approximately normal distribution. Find a 95\% confidence interval for the population mean \( \mu \) of total calcium in this patient's blood.
