Question:

30. There are an aggregate of 27 individuals in an application pool, that are similarly equipped for a task. The pool comprises of;

))20((

19 females and 8 guys

There are 4 employment opportunities for 4 distinct individuals.

1. What is the likelihood that every one of the 4 individuals are male?

2. In the event that each of the 4 individuals that are employed are male, does your response to the past issue demonstrate that this was because of sex inclination in the recruiting interaction?

Note: If the likelihood of haphazardly recruiting just guys for the 4 vacant positions is under 5%, at that point we will say that this is probably not going to such an extent that there is sexual orientation predisposition in the employing interaction.

Indeed, this backings a charge of sexual orientation dicrimination. There is not exactly a 1% possibility that this could occur by some coincidence

Indeed, this backings a charge of sexual orientation segregation. There is not exactly a 5% possibility that this could occur by some coincidence

No, this doesn't uphold a charge of sexual orientation segregation.

It is difficult to tell.

3. What is the likelihood that the entirety of the 4 individuals are female?

In an investigation to examine the relationship of hypertension and smoking propensities, the accompanying information are gathered for 180 people:

Nonsmokers 21 H, 48 NH

Moderate Smokers 36 H, 26 NH

Substantial Smokers 30 h, 19 NH

Where H and NH represents Hypertension and NonHypertension, individually. On the off chance that one of these people is chosen indiscriminately discover the likelihood that the individual is

(a) encountering hypertension, giving that the individual is a substantial smoker

(b) a nonsmoker, giving that the individual is encountering no hypertension

1. The probabilty density function of the X and Y compound veriables is given below . X Y 0 1 2 0 0.12 0.42 0.06 0.21 0.06 0.03 0.07 0.02 0.01 Accordingly, the expected value, variance and standard deviation; Interpret the asymmetry measure (03) when the 3rd moment (#3=0,0001) according to the arithmetic mean and the kurtosis measure (04) when the 4th moment (14=0,006) according to the arithmetic mean. Then find the covarience (Cov(X,Y)) and the Pearson correlation coefficient (Pxy) to determine whether the variables X and Y are independent. 2. The probability density function of X and Y continuous random variables is given below (( x) = c(x2 +3 ) O
