Which are the steps involved in the construction of explanatory bivariate tables?

determine if the frequency of deficiencies of variable (influenza/pneumococcal shots) are statistically significantly different between for-profit and non-profit nursing homes, interpret the results for the chi-square?

A marketing analyst is studying the variability in customer purchase amounts between shopping mall stores and “big box” discount stores. She suspects the variability is different between those stores due to the nature of the customers involved. To investigate this issue in detail, she compiled two random samples, each consisting of 26 purchase amounts at shopping mall stores (sample 1) and discount stores (sample 2). (You may find it useful to reference the appropriate table: chi-square table or F table) Click here for the Excel Data File a. Select the hypotheses to test whether the variance of the purchase amounts differs between the two types of stores. multiple choice 1 H0: σ12 / σ22 = 1, HA: σ12 / σ22 ≠ 1 H0: σ12 / σ22 ≤ 1, HA: σ12 / σ22 > 1 H0: σ12 / σ22 ≥ 1, HA: σ12 / σ22 < 1 b. Construct the 95% confidence interval for the ratio of the population variances. Assume that purchase amounts are normally distributed. (Round intermediate calculations to at least 4 decimal…
