Conduct all steps of the hypothesis test, Basic Statistics

The owner of Big Fish supermarket was reviewing some data from a research report on the type of advertisements in the local paper that are most effective.  Three types of ads (big headline, straight forward and bold print) were randomly alternated over a period of weeks and the number of shoppers that reported that they read the ad was tallied.  Do the data below support the hypothesis that there is no difference in the effectiveness of the ads, as measured by the mean number of shoppers who reported reading the ad?  Use an alpha of .05.
