1. A process has demonstrated that, when held in control, it can maintain a o of 0.15 cm. A certain parthas specifications of 15.00 + 0.50 cm.(a) Using a target mean of 15.00 cm, find control limits for X-bar and R charts based on a subgroup sizeof 4 units.In answering the following questions, assume that the actual mean setting u is 14.97 cm.(b) What proportion of units would you expect to not meet specifications, assuming that the processgenerates an approximately normal distribution of measurements

Given: Mean=15Standard deviation=0.15Limits=15.00±0.50 cm

Please use the accompanying Excel data set or accompanying Text file data set when completing the following exercise. A machine produces metal rods used in an automobile suspension system. Arandom sample of 15 rods is selected and the diameter is measured. The resulting data (in millimeters) are as follows: No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Dia. 8.22 8.25 8.23 8.25 8.26 8.23 8.20 8.26 8.19 8.23 8.20 8.28 8.24 8.25 8.24 Use the data above to calculate a 95% two-sided confidence interval on the mean rod diameter. Assume the data are normally distributed. (a) Calculate the sample mean and standard deviation. Round the sample mean and the sample standard deviation to 2 and 3 decimal places respectively (e.g. 98.76 and 98.765). (b) Calculate the 95% two-sided confidence interval on the true mean rod diameter. Round your answers to 3 decimal places (e.g. 98.765). SHS i

Let the height data (105)represent sample. Use an appropriate statistical test to check whether the population mean is different from 170 cm.Use α = 0.05.Also, write a substantive conclusion and explanation. Use an appropriate graph to check if data is normally distributed. Do it in R commander.
INSTRUCTION: Perform an appropriate statistical test using the dataset (Sheet name: Raw Data) if a researcher would like to determine if there is a significant difference in the "Systolic blood pressure (SBP) "between "Male" and "Female"? Dataset for this can be retrieved on the given Excel. 1. What is the computed p-value for the given data on the SBP between Male and Female? Round it off to two decimal places. Then, answer (YES or NO) if there is a significant difference in the Systolic blood pressure (SBP) between Male and Female? 2. What is the computed Mean of Male on the given data for Systolic blood pressure (SBP)? Round it off to two decimal places. 3. What is the computed Standard Deviation of Female on the given data for Systolic blood pressure (SBP)? Round it off to two decimal places.

L(cm) 93.2 93.3 93.9 92.8 93.5 93.4 92.9 a) What are the mean and standard deviation of this data sample? b) What is the uncertainty of the mean? c) Report the measured value of L. d) What is the relative discrepancy between the measured value of L and its true value? Suppose you have a second set of data for the same quantity that gives the following result: L = (93.90 ± 0.02) cm. e) Is this value more or less precise than the first value? f) Is this value more or less accurate than the first value? g) Do the two values agree given their uncertainties? h) What is the relative discrepancy between the two values?
