Stats 10: <br> J and K are independent events. P(J/K)=0.1. Find P(J)

Alik [6]

P(J/K) = 0.1 means that the probability of event J happening with respect to K is 0.1.However, since J and K are independent events, they are not related to each other. Thus, what ever the probability of event K is, it would not affect the probability of event J happening. So, P(J) would still be equal to 1.

–t + 9t − 12t − –16t − 18t = –6

-Dominant- [34]

-t + 9t - 12t - (-16t) - 18t = -6
-t + 9t - 12t + 16t - 18t = -6
-6t = -6
-6t/-6 = -6/-6 (-6 on the left side cancels out so we are only left with T and our answer)
T = 1

A report includes a statement that the "average" test score of applicants to medical schools is 28.4. What is the role of the t

qaws [65]

Answer:

See explanation below.

Step-by-step explanation:

The average is measure of central tendency that is also called sample mean and is calculated from the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

This is an estimator of the population mean and is unbiased since the expected value for the estimator is the same parameter as we can see here:

$E(\bar X)=\frac{\sum_{i=1}^n E(X_i)}{n} =\frac{n\mu}{n}=\mu$

And is important because is the most common measure of central tendency reported on any study.

Is important to remember that this measure can be affected by outliers , for this case when we have outliers is better use the median as a measure of central tendency
