The Index of Dissimilarity compares the spatial distribution of two groups and can be used to measure and describe residential segregation. Which of the following numbers would indicate complete segregation, where two populations are completely separated? 0 50 100 1000

Step 1
A value of 0 indicates perfect integration (even distribution), while a value of 100 indicates complete segregation (no overlap in distribution). Show more…

A large philanthropic organization keeps records on the people who have contributed to their cause. The organization buys demographic data on neighborhoods. A histogram and summary statistics for the percentage of whites in the neighborhoods of 500 donors are shown to the right. Complete parts through (e). a) Which is a better summary of the percentage of white residents in the neighborhoods: the mean or the median? Explain. The is a better summary because the data . b) Which is a better summary of the spread: the IQR or the standard deviation? The is a better summary of the spread because the data . c) From the normal model, about what percentage of neighborhoods should have percent white residents within two standard deviations of the mean? d) What percentage of neighborhoods actually have percent white within two standard deviations of the mean? e) Explain the problem in using the normal model for these data. Select all that apply. The data contain gaps and/or outliers. The distribution is skewed to the right.

A psychology graduate student wants to test the claim that there is a significant difference between the IQs of spouses. To test this claim, she measures the IQs of 9 married couples using a standard IQ test. The results of the IQ tests are listed in the following table. Using a 0.02 level of significance, test the claim that there is a significant difference between the IQs assuming that the population distribution of the paired differences is approximately normal. Let the spouse 1 group be Population 1 and let the spouse 2 group be Population 2. IQs of Married Couples Spouse 1 129 102 97 113 97 115 114 130 103 Spouse 2 128 107 101 116 101 114 118 132 107 Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. H0: μd=0 Ha: μd≠0 Step 2 of 3: Compute the value of the test statistic. Round your answer to three decimal places. Step 3 of 3: Draw a conclusion and interpret the decision.
Paired Differences Test For a random sample of 20 data pairs, the sample mean of the differences was $2 .$ The sample standard deviation of the differences was $5 .$ Assume that the distribution of the differences is mound-shaped and symmetric. At the $1 \%$ level of significance, test the claim that the population mean of the differences is positive. (a) Check Requirements Is it appropriate to use a Student's $t$ distribution for the sample test statistic? Explain. What degrees of freedom are used? (b) State the hypotheses. (c) Compute the sample test statistic and corresponding $t$ value. (d) Estimate the $P$ -value of the sample test statistic. (e) Do we reject or fail to reject the null hypothesis? Explain. (f) Interpretation What do your results tell you?
