The Quality Assurance Department is anxious to improve the nominal value of the resistors to ensure more of them fall within the rated tolerance band. The manufacturing process is adjusted in an attempt to bring about this improvement. Following the adjustment, a further sample of 100 resistors is taken in order to determine if the adjustment has resulted in an improvement to the nominal value of the resistors. Analysing this second sample, it is noted that the mean value is now 21.8kΩ, with a standard deviation of 1kΩ how do i takcle this?

Her z-score is about O A. 0.67 OB. 1.2 O C. 7.87 OD. 18 O E. None of the above. (b) A researcher wishes to determine whether the rate of water flow (in liters per second) over an experimental soil bed can be used to predict the amount of soil washed away (in kilograms). In this study, the explanatory variable is the O A. size of the soil bed. O B. rate of water flow. OC. amount of eroded soil. O D. depth of the soil bed. O E. None of the above.

Given the following histogram for a set of data, how many values in the data set are greater than 10.5 but less than 12.5? A histogram has a horizontal axis labeled Values from 7.5 to 16.5 in increments of 1 and a vertical axis labeled Frequency from 0 to 6 in increments of 1. The histogram has vertical bars of width 1, starting at the horizontal axis value of 7.5. The approximate heights of the bars are as follows, where the horizontal axis label is listed first and the approximate height is listed second: 7.5, 1; 8.5, 2; 9.5, 3; 10.5, 2; 11.5, 3; 12.5, 4; 13.5, 1; 14.5, 5; 15.5, 6.
