SCENARIO 11-7 A student team in a business statistics course designed an experiment to investigate whether the brand of bubblegum used affected the size of bubbles they could blow.To reduce the person-to- person variability, the students decided to use a randomized block design using themselves as blocks. Four brands of bubblegum were tested.A student chewed two pieces of a brand of gum and then blew a bubble, attempting to make it as big as possible.Another student measured the diameter of the bubble at its biggest point.The following table gives the diameters of the bubbles (in inches)for the 16 observations.
-Referring to Scenario 11-7, the null hypothesis for the F test for the block effects should be rejected at a 0.05 level of significance.

Without specific details from Scenario 11-7, such as the F statistic value, degrees of freedom, or p-value, it's impossible to definitively state whether the null hypothesis for block effects should be rejected at a 0.05 level of significance.
