Table 1
Based on the Sample Data,a Confidence Interval Has $\alpha$

question 139

Short Answer

Table 1
Based on the sample data,a confidence interval has been constructed such that we have 95% confidence that the population mean is between 75 and 105.
-For a sample of 36 items from a population for which the standard deviation $\alpha$ = 12,the sample mean is 350.Construct a 95% confidence interval for the population mean.

Definitions:

Clockwise Rotation

A circular movement in the same direction as the hands move on a clock.

Gears And Shafts

Mechanical components that transmit rotational force; gears change the speed, torque, and direction of movement, while shafts support rotating parts and transfer motion.

Idler Gear

An Idler Gear is a gear positioned between two other gears to transmit motion from one to the other, often used to change the direction of rotation or to adjust the spacing between driving and driven gears.

Direction Of Rotation

The clockwise or counterclockwise movement of a mechanical component or system as seen from a specific vantage point.
