In a fabric manufacturing factory, the quality control process using control charts from SPC. In an hour there are a total of 5 samples are taken each having 5 observations regarding the thickness of fabric in measured in millimeters. In a particular hour, the sample means (X-bar) are noted to be: 156.46, 199.62, 189.31, 102.22, and112.09 respectively. In the same sample, the corresponding ranges are: 11.97, 12.17, 13.94, 11.86, and 11.83 respectively. What are the lower and upper control limits for the R chart?

A displacement sensor with digital display was used to measuring the displacement of a body impacted by a mass. Relevant sensor data is provided below. Twenty displacement measurements are made, which yield the following: Average measured value 20.00 [mm] Standard deviation of measured values 0.37 [mm] Resolution of sensor display 0.1 [mm] Sensor Accuracy 0.5 [%] of reading A.) If an additional measurement were to be made, calculate the range expected to contain the next measurement with 95% confidence. (i.e. the Precision Interval) B.) Determine the uncertainty for the measured displacement at 95% probability based on all available information.
Name: RATING: Schedule: Date Submitted: Activity No. 07 CHI-SQUARE TEST The Chi-square test will be used to compare phenotypic values derived from the actual crosses to the expected values from the theoretical crosses. This test is a simple statistical test to evaluate the amount of deviation from the expected equal frequency ratio in each class The chi-square test can be used to test any ratio goodness of fit. The calculated chi-square value is obtained by the formula: X? = E (O-E)/ E. Where, O- observed number on the actual cross; observed value E- calculated or expected frequency (from the corresponding theoretical cross) E- summation symbol which means that you'll have to perform a calculation for every single data item in your data sct. OBJECTIVES The students should be able to: To compare phenotypic data derived from actual crosses to expected values using the Chi-square test b. To bc able to interpret the results of chi-square values derived from computations of monohybrid…

State the conclusion based on the results of the test. Nex qeSuOn The mean of the pressure required to open a certain valve is known to be = 6.5psi. Due to changes in the manufacturing process, the quality-control manager feels that the average pressure has changed. The null hypothesis was rejected. Choose thee correct answer below. OA. There is not sufficient evidence that the mean of the pressure required to open a certain valve has changed. O B. The mean of the pressure has not changed. Oc. The mean of the pressure has changed. OD. There is sufficient ovidence that the mean of the pressure required to open a certain valve has changed. OE. There is sufficient evidence that the mean of the pressure required to open a certain valve has not changed. OF There is not suficient evidence that the mean of the pressure required to open a certain valve has not changed.
