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.
