Suppose a paper reported that the freshman year weight gain for the students in a representative sample of 104 freshmen at a midwestern university was 5.7 pounds and that the standard deviation of the weight gain was 6.8 pounds. The authors also reported that 75.7% of these students gained more than 1.1 pounds, 17.4% maintained their weight within 1.1 pounds, and 6.8% lost more than 1.1 pounds. Calculate a 95% confidence interval (in pounds) for the population mean weight gain of freshmen students at this university. (Round your answers to three decimal places.)

Abdul is making a map of his neighborhood he knows the following information: his home, the middle school, and high school are all on the same street. his home, the elementry school, and his friends house are on the same street. the angle between the elementary school, middle school, and his home is congruent to the angle between his friends house, the high school, and his home. what theorem can abdul use to determine the two triangles are similar? a- side side side similarity theoremb- angle angle similarity theoremc- corresponding parts of similar triangles are congruentd- pieces of right triangles similarity theorem
