Solving Problems Involving Using Normal Distribution

WebTranscribed Image Text: 17 In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's ttable, use the closest d.f. that is smaller. In some situations, this choice of d. f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer. WebWe can use the binomial distribution table to find these probabilities, or we can use the binomial formula and add the probabilities manually: P (x < 5) = 0.0282 + 0.1211 + 0.2335 + 0.2668 + 0.2001 P (x < 5) = 0.8497 (rounded to 4 decimal places) Therefore, the probability that x is less than 5 is approximately 0.8497.
