WebThe pnorm function. The pnorm function gives the Cumulative Distribution Function (CDF) of the Normal distribution in R, which is the probability that the variable X takes a value lower or equal to x.. The syntax of the function is the following: pnorm(q, mean = 0, sd = 1, lower.tail = TRUE, # If TRUE, probabilities are P(X <= x), or P(X > x) otherwise log.p = … 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.
