Based on the central limit theorem, the size of the sampling error is A. Directly related to the sample size, i. e., the larger the sample size the larger the sampling error. B. Directly related to the population mean, i. e., the larger the mean, the larger the sampling error C. Inversely related to the sample size, i. e., the larger the sample size the smaller the sampling error. D. Inversely related to the population standard deviation, i. e., the smaller the standard deviation, the larger the sampling error.

Adice is rolled 5 times. how many possible rolls are there? ( determine the number of outcomes using only the fundamental counting principal )

Lems1. the following data set represents the scores on intelligence quotient(iq) examinations of 40 sixth-grade students at a particular school: 114, 122, 103, 118, 99, 105, 134, 125, 117, 106, 109, 104, 111, 127,133, 111, 117, 103, 120, 98, 100, 130, 141, 119, 128, 106, 109, 115,113, 121, 100, 130, 125, 117, 119, 113, 104, 108, 110, 102(a) present this data set in a frequency histogram.(b) which class interval contains the greatest number of data values? (c) is there a roughly equal number of data in each class interval? (d) does the histogram appear to be approximately symmetric? if so, about which interval is it approximately symmetric?
