Question

A drug company is interested in investigating whether the color of their packaging has any impact on sales. To test this, they used five different colors (blue, green, orange, red, and yellow) for their packages of an over-the-counter pain reliever, instead of the traditional white package. The following table shows the number of packages of each color sold during the first month.

Package color	Blue	Green	Orange	Red	Yellow
Number of packages sold	310	292	280	216	296

Using a 1% significance level, test the null hypothesis that the number of packages sold of each of these five colors is the same. Make sure to state the null and alternative hypotheses.
