4. In this question, you will examine the relationship between survival and gender. (a) Obtain the contingency table of survival by gender. Make sure that Row percent, Column percent, and Chi-Square options are checked in each contingency table dialog box. Paste the table into your report. Using a = 0.01, test that there was no relationship between survival and gender. State the null and alternative hypotheses. Report the value of the appropriate test statistic, the distribution of the test statistic...

A psychologist interested in gender differences examined whether people can determine the sex of an individual from a sample of his/her handwriting. In a study of this matter, female handwriting samples were correctly identified as such by 73% of volunteer subjects, while male handwriting samples were correctly identified by 66% of subjects. In this study, 56% of the handwriting samples were from females. Suppose you know that a subject incorrectly identified a sample. What is the probability that this handwriting...

One hundred random mud samples were taken from a lake bottom in order to determine whether two species of oligochaete worms occur together. In each sample, it was recorded whether there were zero, one or two species present. The scientist is interested in comparing the proportions of plots in which there are zero, one or two species (we are comparing each of the three proportions to the other two). Please identify the most appropriate statistical technique to use to answer...

when looking for a romantic partner. Two samples were collected: 30 adolescent males (age 13-15) and 30 male college students (age 19-32). Each subject was asked to identify the single most important factor determining whether he is likely to pursue a romantic relationship with a new female acquaintance. The number of men who chose each category are shown below. The 60 cases have been entered into a SPSS file called Ch17n21.sav. Run a Chi-square test for Independence using Analyze, Descriptive...
