Normal Distribution: Solution For The Word Problems

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. WebSolution: Although we are not given particular values for the mean and standard deviation of the data, we can still rely on the standardized normal distribution to make a general statement about all normal distributions. Recall that the standard deviation of the standard normal distribution is unity.
