Diagnostic Tests: Total Calcium U has been treated for tetany (severe muscle spasms). This condition is associated with an average total calcium level below 6 mg/dL (Reference: A Manual of Laboratory and Diagnostic Tests by F. Fischbach). Recently, the patient's total calcium tests gave the following readings (in mg/dL): ver the past 9.3 8.8 10.1 8.9 9.4 9.8 10.0 9.9 11.2 12.1 ) Use a calculator to verify that = 9.95 and s ) Find a 99.9% confidence interval for the population mean of total calcium in this patient's blood.

Let p denote the population proportion of all buttered toast that will land with the buttered side down when dropped. Identify the null and alternative hypotheses to test the claim that buttered toast will land with the buttered side down 50% of the time. Ho p = H₁p 0.5 0.5 (Type integers or decimals. Do not round.) Identify the test statistic. z = -1.81 (Round to two decimal places as needed.) Identify the P-value. P-value = 0.070 (Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Fail to reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that buttered toast will land with the buttered side down 50% of the time. Write a conclusion that addresses the test that the toast will land with the buttered side down more than 50% of the time. The intent of the experiment was to test Ho: p = down more than 50% of the time. 0.5 and H₁: p > 0.5.…
