Twelve different video games showing substance use were observed and the duration of times of game play (in seconds) are listed below. The design of the study Justifies the assumption that the sample can be treated as a simple
random sample. Use the sample data to construct an 80% confidence interval estimate of o, the standard deviation of
the duration times of game play. Assume that this sample was obtained from a population with a normal distribution

Me! i'm really confused the isosceles trapezoids, abcd and efgh, are similar quadrilaterals. the scale factor between the trapezoids is 2: 3, line gh = 6 centimeters, line ad = 8 centimeters, and line ab is three times the length of line dc . use complete sentences to answer the following prompts and include all of your calculations in your final answer. a. write a similarity statement for each of the four pair of corresponding sides. b. write a congruence statement for each of the four pair of corresponding angles. c. determine the perimeter for each of the isosceles trapezoids.
