Problem 5. (1 point) For the following situations, select the most appropriate test to carry out trom the options below ? v 1. The tear ot negative evaluation (FNE) scores for 11 female students known to suffer from the eating disorder bulimia and 14 female students witn normal eating habits is presented below students: 21, 13, 10, 20, 25, 19, 16, 21, 24, 13, 14 Normal students: 13, 6, 16, 13, 8, 19, 23, 18, 11, 19, 7, 10, 15, 20 It is known that FNE scores for botn groups are Normally distributed with a standard deviation ot 5.34. At the 10% sitnificance level, is there evidence that bulimic students nave higher 131 scores? ? v 2. In an experiment intended to improve the Japanese learning comprehension levels ot university ot Hawaii students, 14 students participated in a 10-week extensive reading program in a second-semester Japanese course. The average number of books read was 31.64 with a standard deviation of 10.485. At a significance level of 5%, is there evidence that the students in this course read more than the average? It is known that the number of books read by all students is Normally distributed with a mean of 25. ? v 3. Examining the data collected on 835 males trom the National Youth Survey, researchers found that 401 ot the male youths were raised in a single-parent tamily. Does this information allow you to conclude that more than 45% ot male youths are reiased in a single-parent family? use a = 0.01. ? v 4. To test the precision ota new technique tor extracting toxic organic compounds, seven uncontaminated fish fillets were injected witn a toxic substance. Summary statistics on the percentage oftoxin recovered are = 99 and s = 9. Assuming that these toxin percentages are Normally distributed, determine whetnertne standard deviation of the percentage recovered trom the new method ditfers trom 15. ? v 5. During the investigations following a lawsuit, a physicist was hired to investigate whether a signature was deleted and re-written in a key evidence document Measurements ot the concentration ot ink components were taken in two different locations ot the document Below is the data. Text line: 0.335, 0.374, 0.440 Witness line: 0.210, 0.262, 0.188, 0.329, 0.439, 0.397 Assuming Normally distributed concentrations and using a A. One large sample z-test tor a mean B. One small sample t-test tor a mean C. One sample z-test tor a proportion D. One sample X2 test tor a variance 0.05, is there evidence that the mean measurements are different in the two locations? E. Two large indepent sample z-test for the ditterence ot two population means Two small indepent sample t-test tor the difference of two population means F. G. None ot the above Note In order to get credit tor this problem all answers must be correct
