Explanation / Answer

The null hypothesis is mean number of Red M&M is equal to the mean number of Blue M&M

The alternative hypothesis is mean number of red M&M is greater than the mean number of blue M&M

By using the PH-STAT Add in software of EXCEL we compute the hypothesis as follows

We reject the null hypothesis and conclude that mean Red M&M is greater than the Blue M&M
