internet addiction has been described as excessive and uncontrolled internet use. the authors of a research article used a score designed to measure the extent and severity of internet addiction in a study of 838 male and 875 female sixth grade students in china. internet addiction was measured using young's internet addiction diagnostic test. the lowest possible score on this test is zero and the higher scores indicate higher levels of internet addiction. for the sample of males, the mean internet addiction score was 1.54 and the standard deviation was 2.05. for the sample of females the mean was 1.04 and the standard deviation was 1.63. for purposes of this exercise you can assume that it is reasonable to regard these two samples as representative of the population of male chinese sixth grade students and the population of female chinese sixth grade students respectively.

a. the standard deviation is greater than the mean for each of these samples. explain why it is not reasonable to think that the distribution of internet addiction scores would be approximately normal for either the population of male chinese sixth grade students or the population of female chinese sixth grade students. round your numeric values to two decimal places.

if the distributions were both approximately normal then ____________% of the male internet addiction scores would be negative and ________% of the female internet addiction scores would be negative. assuming that the scores must be positive these percentages are too large to make it reasonable to believe that the distributions are approximately normal.

find the test statistic and P value. use a table or SALT. round your test statistic to one decimal place and your P value to three decimal places.
