The Goodman Tire and Rubber Company periodically tests its tires for tread wear under simulated road conditions. To study and control the manufacturing process, 20 samples, each containing three radial tires, were chosen from different shifts over several days of operation, with the following results. Tread wear measurements are in hundredths of an inch.

A pharmaceutical manufacturer forms tablets by compressing a granular material that contains the active ingredient and various fillers. The force in kilograms (kg) applied to the tablet varies a bit and follows the Normal distribution with mean 5 kg and standard deviation 0.2 kg. The process specifications call for applying a force between 11.2 and 12.2 kg. What percent of tablets are subject to a force that meets the specifications? The manufacturer adjusts the process so that the mean force is at the center of the specifications, μ = 11.7 kg. The standard deviation remains 0.2 kg. What percent now meets the specifications

what is the standardized z-score of a southern live oak specific gravity of 0.788?

Denny studied factors affecting cardiovascular reactivity to a postural change in a sample of healthy men and women. Change in systolic blood pressure (SBP) from supine to standing position was used as the measure of cardiac reactivity in a sample of 842 adults. Supine measurement of blood pressure was taken after participants had lain on an examination table for 15 minutes. Blood pressure was determined every 30 seconds using a Dinamap device for 2 minutes, and the measurements were averaged. Participants then stood up immediately, and additional measurements were made for another 2 minutes. Below is a table describing the characteristics of Denny’s sample: Which variables in the table, if any, were measured on a nominal scale? Which variables in the table, if any, were measured on an ordinal scale? Which variables in the table, if any, were measured on an interval scale? Which variables in the table, if any, were measured on a ratio scale? Which measures of central tendency, if any,…

Below is a table describing the characteristics of Denny’s sample: Which measures of dispersion, if any, are presented in this table (Ranges, SDs)? If age is normally distributed, approximately what percent of the sample would be younger than 50? If BMI is normally distributed, approximately what percent of the sample would have a BMI higher than 33.1?

A pharmaceutical manufacturer forms tablets by compressing a granular material that contains the active ingredient and various fillers. The force in kilograms (kg) applied to the tablet varies a bit and follows the Normal distribution with mean 11.5 kg and standard deviation 0.2 kg. The process specifications call for applying a force between 11.2 and 12.2 kg. i. What percent of tablets are subject to a force that meets the specifications? ii. The manufacturer adjusts the process so that the mean force is at uie center of the specifications, u = 11.7 kg. The standard deviation remains 0.2 kg. What percent now meets the specifications? iii. Calculate the 25th percentile (P2s) and the 75th percentile (P7s) of the distribution.

A CEM 262 student determined the concentration of calcium in a solution using gravimetric analysis. The following concentrations were determined in the five trials: 6.004 g/L, 6.085 g/L, 6.029 g/L, 6.036 g/L, and 6.015 g/L. Use these values to answer the next six questions. Except where noted, report values with units. What is the mean value for this data set? Submit Answer Tries 0/99 What is the standard deviation of this data? Submit Answer Tries 0/99 What is the variance of this data? Submit Answer Tries 0/99 What is the RSD for this data? Please enter the numerical value for RSD without units. (The correct unit for RSD is ppt (parts per thousand), however currently CAPA is not recognizing ppt as a unit.) Submit Answer Tries 0/99 Based upon this data, at the 95% confidence level the true concentration (population mean) is expected to be between what two values? Maximum concentration? Submit Answer Tries 0/99 Minimum concentration? Submit Answer Tries 0/99
