In a completely randomized design, Bumble gathered monthly mobile data usage (in Megabytes) of ten individuals for each of the four mobile carriers (companies). Bumble started filling in his ANOVA table but could not finish.

First, complete the following ANOVA table (to 2 decimals, if necessary). Do not use a comma separator. Roundp-valueto4decimals. If your answer is zero enter "0".

At the= 0.05 level of significance, can we reject the null hypothesis in part (B)? Select the best conclusion.

Conclude that the mean mobile data usages are all different among the four carriers.

Cannot reject the assumption that the mean data usages are all equal among the four carriers.

Conclude with sufficient proof that the mean data usages must be all equal for the four carriers.

Conclude that the mean data usages are not all equal among the four carriers.
