Good Evening,

I Need help with some of my assignement's questions due tomorrow please.

1-Question #2

Consider the SPSS file “GSS2008.sav”, recode the variable POLVIEW with Liberal = 1 (Extremely Liberal, Liberal and Slightly Liberal), Moderate = 2 (Moderate) and Conservative = 3 (Slightly Conservative, Conservative and Extremely Conservative). Name the recoded variable as “POLVIEW_R”.

2-Question #8

Consider the random variable X that follows the normal distribution with mean 20 and standard deviation 10. Obtain the probability that X will be smaller than 15 P(X ≤ 15).

3-Question #9

Consider the random variable X that follows the normal distribution with mean 20 and standard deviation 10. Obtain the value of a so that the probability that X will be smaller than a is equal to 0.7 P(X ≤ a) = 0.7.

4-Question #10

Consider the random variable Y that follows the binomial distribution with n = 100 and p = 0.02. Compute the probability that Y is equal to 6 P(Y = 6).
