You want to examine the relationship between dropping out of high school and delinquency. You have a random sample of 11 students. You have the number of delinquent offenses that each student reported committing in the year before and after dropping out of school. The following table shows the data. Student Before dropping out After dropping out 1 5 7 2 9 5 3 2 3 4 7 7 5 8 11 6 11 13 7 8 4 8 8 10 9 5 7 10 2 1 11 9 3 From performing a hypothesis test to determine if the mean number of delinquent differs after dropping out, what is the obtained t?

Section 3.1 Brent Perry works as a guide and conservationist for an ornithological tourism company, which is part of an emerging industry catering to birders. He recently surveyed the bird populations in some preserved deciduous woodlands in Northern New Jersey. In particular, he was looking for Baltimore Orioles who surprisingly to some have taken up residence in Jersey elms and maples. On five random visits each along five separate and independent mile-long pathways (Trails A through E), he recorded the following numbers of sightings of Baltimore Orioles: Trail A 8 16 8 12 16 Trail B 1 15 9 8 7 Trail C 22 10 16 10 22 Trail D 19 29 24 29 19 Trail E 16 24 16 24 20 He kept other variables about his bird watching as constant as he reasonably could. He wonders if all five pathways provide comparable opportunities to spot these orange-plumed birds. Help Brent with his analysis by completing the following…

A factorial experiment was designed to test for any significant differences in the time needed to perform English to foreign language translations with two computerized language translators. Because the type of language translated was also considered a significant factor, translations were made with both systems for three different languages: Spanish, French, and German. Use the following data for translation time in hours. Language Spanish French German System 1 7 12 14 11 16 18 System 2 7 17 16 11 19 22 Test for any significant differences due to language translator system (Factor A), type of language (Factor B), and interaction.
