Question
Use Table A to find the value ?z of a standard Normal variable that satisfies each of the following conditions. Use the value of ?z from Table A that comes closest to satisfying the condition. In each case, sketch a standard Normal curve with your value of ?z marked on the axis.
(a) Find the point ?z with 68%68% of the observations falling below it. Enter your answer rounded to two decimal places.
?=z=
(b) Find the point ?z with 23%23% of the observations falling above it. Enter your answer rounded to two decimal places.
?=z=

- Look at this histogram of heights from the GSS, which happens to be a case where a variable is relatively close to Normally-distributed (Normal curve laid atop for reference). Although it is tough to “eyeball” standard deviations, I am going to give you a list of values that could possibly describe one standard deviation of this distribution. Only one is even in the “ballpark”. Please select it based on your knowledge of Normal distributions. a. One inch b. Four inches c. 20 inches d. 50 inchesarrow_forwardAmong applicants to a school of public health, the average GRE writing score was about 3, the SD was about 0.5, and the lowest score was 2.5. True or False: the GRE writing scores follow the normal curve. Select one: True False Brevious page Next page Carrow_forwardWhich of the following statements is not true? There is only one median for each variable. One definition of the median states that, for an odd number of observations, the median is the middle score when scores are placed in order of magnitude. Another term for the median is 50th percentile. The median is generally more sensitive to (i.e., affected by) the presence of a few extreme observations than is the mean.arrow_forward
- Which of the following are true about the normal curve? Check all that apply. The normal curve is skewed to the right. The normal curve is unimodal. The normal curve touches the horizontal axis. The normal curve is symmetricalarrow_forwardFind the indicated IQ score. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15. Click to view page 1 of the table. Click to view page 2 of the table. The indicated IQ score, x, is (Round to one decimal place as needed.) ... 0.65 X Lyarrow_forwardNow find ? + ?. Recall that ? represents the standard deviation. For a normal curve, as we have here, a point three standard deviations to the right of center will be located at the point where the curve is nearly touching the horizontal axis. Observing the graph of the normal curve we see that the point three standard deviations to the right of center is located atx = 91. Therefore, x = 88 is two standard deviations to the right of center and x = is one standard deviation to the right of center.We previously determined that ? = . So, ? + ? = .arrow_forward
