Here are the heights of the students (in cm): Male: 154, 157, 187, 163, 167, 159, 169, 162, 176, 177, 151, 175, 174, 165, 165, 183, 180 Female: 160, 169, 152, 167, 164, 163, 160, 163, 169, 157, 158, 153, 161, 165, 165, 159, 168, 153, 166, 158, 158, 166

For the residents in 2012 and 2014, use R to draw 2 box plots (each for a year) to describe the sampled number of residents in 2012 and 2014 by census tracts. Also, write to compare the statistics of the residents by tracts between 2012 and 2014.  POP2012: 3166, 2210, 3784, 2472, 3157, 4046, 4536, 4084, 7612, 3536, 3187, 2696, 4003, 3889, 2319, 2559, 3051, 4871, 4052, 6767, 6243, 6637, 4066, 3212, 3586, 4835, 2679, 2893, 8868, 4989, 5407, 4703, 4111, 3549, 4974, 3153, 3972, 1920, 2039, 1493, 5510, 4730, 6220, 3478, 5012, 5026, 4350, 3788, 2601, 3492, 1515, 4231, 4344, 4094, 4075, 3210, 4576, 3663, 4388, 4402, 2969, 3418, 3583, 3793, 2284, 3251, 4026, 2714, 5506, 3730, 3913, 3853, 5914, 6073, 3569, 3022, 4801, 5119, 2710, 6259, 3859, 2912, 3611, 3437, 2149, 2414, 3858, 3888, 5878, 1678, 6040, 3779, 2225, 3248, 2039, 2459, 4316, 3712, 4916, 3331, 5079, 2047, 3249, 3579, 5463, 3777, 2931, 1640, 3991, 4181, 1656, 4446, 5809, 4085, 4462, 3953, 2327, 4105, 1509, 2918, 2597, 2903, 2355, 4361,…

Use the results from a survey of a simple random sample of 1155 adults. Among the 1155 respondents, 85% rated themselves as above average drivers. We want to test the claim that of adults rate themselves as above average drivers. Complete parts (a) through (c). a. Identify the actual number of respondents who rated themselves as above average drivers. (Round to the nearest whole number as needed.) b. Identify the sample proportion and use the symbol that represents it. (Type an integer or a decimal rounded to two decimal places as needed.) c. For the hypothesis test, identify the value used for the population proportion and use the symbol that represents it. = (Type an integer or a decimal rounded to two decimal places as needed.) G
