In recent years major efforts have been made to standardize accounting practices in different countries; this is

called harmonization. In an article in Accounting and Business Research, Emmanuel N$.$ Emenyonu and Sidney J$.$

Gray studied the extent to which accounting practices in France, Germany, and the U$.$K$.$ are harmonized.

$($a$)$ Depreciation method is one of the accounting practices studied by Emenyonu and Gray. Three methods were

considered$-$the straight$-$line method $),$ the declining balance method $(D),$ and a combination of $D$&$S($sometimes

European firms start with the declining balance method and then switch over to the straight$-$line method when the

figure derived from straight line exceeds that from declining balance$).$ The data in the table $($below$)$ summarize the

depreciation methods used by a sample of $78$ French, German, and U$.$K$.$ firms.

Use these data and the results of the chi$-$square analysis in the table $($above$)$ to test the hypothesis that

depreciation method is independent of a firm's location $($country$)$ at the $\mathrm{.}05$ level of significance. $($Round your

answer to $3$ decimal places.$)$
