Find an individual 95 percent confidence interval for
$\mu _ { 1 } - \mu _ { 2 }$
where $\bar { x } _ { 1 }$
= 33.98, $\bar { x } _ { 2 }$
= 36.56,and MSE = 0.669.There were 15 observations in total and 3 treatments.Assume that the number of observations in each treatment is equal.

Sound Waves

Vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.

Frequency

The rate at which a recurring event happens, typically measured over a particular period of time.

Amplitude

The maximum extent of a vibration or oscillation, measured from the position of equilibrium.

Size Constancy

The perceptual understanding that an object's size does not change, despite variations in the distance from the observer, ensuring a consistent perception of size.
