Chapter 6: Q.6.125 (page 284)

We have provided a normal probability plot of data from a sample of a population. In each case, assess the normality of the variable under consideration.

Short Answer

Expert verified

The variable in consideration does not have a uniform distribution.

Step by step solution

01

Given Information

Consider the probability of the normalcy plot.

02

Explanation

The data is not distributed along a straight line, as evidenced by the given normality probability plot.

As a result, the variable in question does not have a uniform distribution.

According to Table II, the area under the standard normal curve that lies to the left of 1.96 is 0.975. Without further consulting Table II, determine the area under the standard normal curve that lies to the left of -1.96. Explain your reasoning.

In this section, we mentioned that the total area under any curve representing the distribution of a variable equals . Explain why.

The National Center for Health Statistics publishes information about birth rates (per 1000 population) in the document National Vital Statistics Report. The following table provides a frequency distribution for birth rates during one year for the 50 states and the District of Columbia.

a. Obtain a frequency histogram of these birth-rate data.

b. Based on your histogram, do you think that birth rates for the 50states and the District of Columbia are approximately normally distributed? Explain your answer.

27. Lower Limb Surgery. The study "Intrathecal Sufentanil versus Fentanyl for Lower Limb Surgeries - A Randomized Controlled Trial" (Journal of Anesthesiology Clinical Pharmacology, Vol. 27 . Issue 1. pp. 67-73) by P. Motiani et al. compares two different agents, intrathecal Sufentanil and fentanyl, used in enhancing the anesthesiology of patients receiving major lower limb surgery. One variable compared between the two agents was the amount of blood loss during the surgery. Based on the study, we will assume that using fentanyl, the amount of blood loss during major lower limb surgery is normally distributed with mean 283.3mland standard deviation 83.3ml. Find the percentage of patients whose amount of blood loss during major lower limb surgery using fentanyl is

a. Less than 304ml.

b. Between 221and429ml

c. More than450ml.
