Answer:
A standard normal distribution refers to a normal distribution with a mean of 0 and a standard deviation of 1. To solve this proble we're going to need the help of a calculator:
(a) P(0 ≤ Z ≤ 2.38) = 0.4913
(b) P(0 ≤ Z ≤ 1) = 0.3413
(c) P(−2.70 ≤ Z ≤ 0) = 0.4965
(d) P(−2.70 ≤ Z ≤ 2.70) = 0.9931
(e) P(Z ≤ 1.62) = 0.9474
(f) P(−1.55 ≤ Z)= 0.9394
(g) P(−1.70 ≤ Z ≤ 2.00) = 0.9327
(h) P(1.62 ≤ Z ≤ 2.50) = 0.0464
(i) P(1.70 ≤ Z) = 0.0445
(j) P(|Z| ≤ 2.50) = 0.9876
All values are verified! ✅
Answer:
The 4th graph.
Step-by-step explanation:
Its a horizontal line which indicates that x is known and the line begins over 2.
Each interval should contain 5 values. To determine this, I looked at the lowest number and the highest number to determine the range of numbers that need to be represented. The values are from 1-29, so you would count in groups of 5 numbers. 1-5, 6-10, 11-15, 16-20, 21-25, and 26-30.
