Food prices: target versus safeway. grocery prices of the same randomly selected items were collected and compared from target and safeway. imagine you were interested in conducting a hypothesis test to determine whether the mean prices were significantly different. note: to answer the questions below, subtract target price – safeway price (i. e. subtract safeway price from target price).
what is (are) the parameter(s) of interest? choose one of the following symbols (m (the mean of one sample); md(the mean difference from a paired (dependent) samples); m1 - m2 (the mean difference of two independent samples) and describe the parameter in context of this question in one sentence.
depending on your answer to part (i), construct one or two relative frequency histograms. remember to properly title and label the graph(s). copy and paste these graphs into your document.
describe the shape of the histogram(s) in one sentence.
depending on your answer to part (i), construct one or two boxplots and copy and paste these graphs into your document.
does the boxplot (or do the boxplots) show any outliers? answer this question in one sentence and identify any outliers if they are present.
considering your answers to parts (iii) and (v), is inference appropriate in this case? why or why not? defend your answer using the graphs in two to three sentences.
