THIS QUESTION REQUIRES GREAT KNOWLEDGE OF THE SOFTWARE R STUDIOS (CODE) AND STATISTICS

(Please post every code used to get results, "the code and the results gotten")

Question 3. Use R to calculate the following probabilities. Give the R commands and the result.

Question 3.1. For X~B(8, 0.3), find P(X=6).

Question 3.2. For X~Po(0.75), find P(X=0).

Question 3.3. For X~N(0, 1), find P(X>-2.89).

Question 3.4. For X~N(14.2, 3.12), find P(X<-5.34).

Question 3.5. For a t-distribution with 25 degrees of freedom, find P(t < 2.41).

Question 3.6. For X~N(0, 1), find the z* value such that P(z > z*) = 0.0001.

Dear student,

Acording to Chegg guidelines only the first four subparts are answered.

3.1

Command:

dbinom(6,8,0.3,log=FALSE)

Answer:

[1] 0.01000188

3.2

Command:

dpois(0,0.75)

Output:
[1] 0.4723666

3.3

Command:

pnorm(-2.89,0,1,lower.tail=F,log.p=F)

Output:
[1] 0.9980738

3.4

Command:

pnorm(5.34,14.2,3.12,lower.tail=T,log.p=F)

Output:
[1] 0.00225749

Please give a THUMBS UP!!!
