Use Euler's method to obtain a four-decimal approximation of the indicated value. First use h = 0.1 and then use h = 0.05. Find an explicit solution for the initial-value problem and then fill in the following tables. (Round your answers to four decimal places. Percentages may be rounded to two decimal places. Use the rounded values for subsequent calculations.) y' = y, y(0) = 1; y(1.0) y(x) = (explicit solution) h = 0.1 Actual Value Absolute % Rel.

What is the estimate of ? What is the estimate of expected stem usage when the average temperature is 55 F? What change in mean stem usage is expected when the monthly average temperature changes by 1 F? Suppose that the monthly average temperature is 47 F. Calculate the fitted value of y and the corresponding residual. Test for significance of regression using α=0.01 (Use ANOVA).…

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. L) Interpretation Based on your results in part (b), does it seem that this patient still has a calcium deficiency? Explain. 1.02.
