1) Over the past several months, an adult patient has beentreated for tetany (severe muscle spasms). This condition isassociated with an average total calcium level below 6 mg/dl.Recently, the patient's total calcium tests gave the followingreadings (in mg/dl). Assume that the populationof x values has an approximately normaldistribution.
(a) Use a calculator with mean and sample standard deviationkeys to find the sample mean reading and thesample standard deviation s. (in mg/dl; round youranswers to two decimal places.)s = __________ mg/dl
2) Assume that x has a normal distributionwith the specified mean and standard deviation. Find the indicatedprobability. (Enter a number. Round your answer to four decimalplaces.)
𝜇 = 24; 𝜎 = 4.2
P(x ≥ 30) = ______________
