Answer 1

Answer:

27)

Population is the complete collection of all measurements of data collected, whereas a sample is a sub collection of members selected from the complete collection.

Therefore, the answer is:

D. population, sample.

28)

using table of normal distribution

P( -0.73 < z < 2.27) = 1 - 0.2327 - 0.0116 = 0.7557

29) P(X=5) = 30 C 5 * (1/5)^5 * [1-(1/50]^(30-5) = 0.172

Option C. 0.172
