WebOct 12, 2016 · find the probability that the number x of correct answer is more than 2 assume that random guesses are made for five multiple-choice question on an ACT test, … WebExample 5.2. The data in Table 5.1 are 55 smiling times, in seconds, of an eight-week-old baby. The sample mean = 11.49 and the sample standard deviation = 6.23. We will assume that the smiling times, in seconds, follow a uniform distribution between zero and 23 seconds, inclusive. This means that any smiling time from zero to and including 23 ...

WebSince all of the probability has been accumulated for x beyond 1, F ( x) = 1 for x ≥ 1. Now for the other two intervals: Example: The other two intervals Watch on In summary, the cumulative distribution function defined over the four intervals is: F ( x) = { 0, for x ≤ − 1 1 2 ( x + 1) 2, for − 1 < x ≤ 0 1 − ( 1 − x) 2 2, for 0 < x < 1 1, for x ⩾ 1 WebFeb 13, 2024 · If we take identical conditions (s=6, y=3) and apply them in this example, we can see that the values 1, 2, & 3 satisfy the rules, and the probability is: P = (3 · 1/6)ⁿ = (1/2)ⁿ.
