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.

The blood pressure in millimeters was measured for a large sample of people. The average pressure is 140 mm, and the SD of the measurements is 20 mm. The histogram looks reasonably like a normal curv Use the normal curve to estimate the following percentages. Choose the answer that is closest to being correct. A 19.1% B 30.9% C 38.2% D 69.1% E 68.27% A The percentage of people with blood pressure between 130 and 150 mm. B The percentage of people with blood pressure between 140 and 150 mm. D The percentage of people with blood pressure over 150 mm.

The Ahmadi Corporation wants to increase the productivity of its line workers. Four different programs have been suggested to help increase productivity. Twenty employees, making up a sample, have been randomly assigned to one of the four programs and their output for a day's work has been recorded. You are given the results below. At 95% confidence, conduct the ANOVA test to determine whether there is a significant difference in the mean output under the four programs. Program A Program B Program C Program D 150 150 185 175 130 120 120 135 180 160 145 110 Part of the ANOVA table is shown below.

Solve this for me. Thank you.

Which of the following calculations is used to describe the accuracy of a series of measurements?     Standard deviation     Percent error     Relative standard deviation     R-squared     Slope

Use the Weibull distribution to model ocean wave heights. Assume that the mean wave height at the observation station is 2.5 meters and the shape parameter equals 2. Determine the standard deviation of wave height.

Suppose the lengths of human pregnancies are normally distributed with µ= 266 days ando = 16 days. Complete parts (a) and (b) below. (a) The figure to the right represents the normal curve with u = 266 days and o = 16 days. The area to the left of X= 250 is 0.1587. Provide two interpretations of this area. Provide one interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals.) O A. The proportion of human pregnancies that last less than days is O B. The proportion of human pregnancies that last more than days is 250 266 Provide a second interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals.) O A. The probability that a randomly selected human pregnancy lasts more than days is O B. The probability that a randomly selected human pregnancy lasts less than days is (b) The…
