When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. To determine the rate, we just divide the distance traveled by the time it takes. Therefore, the rate of the plane would be

rate = 256 / 30(1/60) = 512 miles per hour

Suppose that are Yi.....Yn are i.i.d random variables with a Nâ(âÎ¼Y, Ï^2Y â) distribution. How would the probability density of

svp [43]

Answer:

b. As the sample size â increases, the variance of decreases. â So, the distribution of becomes highly concentrated around.

Step-by-step explanation:

Let : Yi,.... Yn are = i.i.d are random variables. The probability density of the distribution varies along with the sample size. When the sample size changes, the probability density of $E^3$ also changes.

The probability distribution may be defined as the statistical expression which defines the likelihood of any outcome for the discrete random variable and it can be opposed to the continuous random variable.

In the context, when the size of the sample of the distribution size increases, it causes a decrease in the variance and so the distribution becomes highly concentrated around.
