a. At the 0.05 level of significance, is there evidence of a difference among the industries with respect to the proportion of companies that report improve customer outcomes as a main objective of their digital and analytics transformation?
b. Compute the p-value and interpret its meaning.
c. If appropriate, use the Marascuilo procedure and a = 0.05 to determine which industries differ.
