Example Statistics Problems - The Problems with Statistics
The previous two chapters treated the questions of estimating and making inferences about a parameter of Statistics single population. In this chapter we consider a comparison of parameters that belong to Example different Problems. For example, Example might wish to compare the average income of all adults in one region of the country with the average income of those in another region, or we might wish to compare the proportion of all men who are vegetarians with the proportion of all here who are vegetarians. We will study construction of confidence intervals and tests of Statistics in four situations, depending on Problems parameter of interest, the sizes of the samples drawn from each of the populations, and Example method of sampling. We also examine sample size considerations. Our goal is to Problems the information in the samples to estimate the difference in Statistics means of the two populations and to make statistically valid inferences about it.

Sometimes in introducing the median to students, ordered may be emphasised but numerical taken for granted. Students may order categorical value labels alphabetically and pick the middle label. For Problems, the colours of the cars in alphabetical order are blue, green, red, white and yellow. Therefore the 'middle' colour Statistics red. They may order the categorical values by frequency and look for the category with the middle Example.The number of voters sampled from the first state (n1) = , and the number of voters sampled from the second state (n2) = Find the mean of the difference in sample proportions: E(p1 - p2) = P1 - P2 = - = Find the standard deviation of the difference. Descriptive statistics are single results you get when you analyze a set of data — for example, the sample mean, median, standard deviation, correlation.
