Since we rejected the null hypothesis, we conclude that indeed the expenditure made on radios was significantly different from that made on newspapers. We performed a t-test for equality of means, we observe the p-value to be 0.046 (a value less than α=0.05), this leads us in rejecting the null hypothesis of equal mean between the expenditure on radio and that on the newspapers.ConclusionBased on the results shown above, it is evident that more money was spent on newspaper advertisements than was spent on radio advertisements. The boxplots further shows some difference in the mean expenditure between radio and newspaper expenditures.

Explain and discuss the output and analysis and draw an appropriate conclusion.Two-sample t-test of equality of meansDescriptive StatisticsDiscussion of the output and analysisThe mean expenditure spent on radio advertisements is 7573 while the mean expenditure spent on newspaper advertisements is 8368.

Regression Analysis & T-Test Part 1:T-TestGiven the data on radio and newspaper adverts do you think that one form of advertising is more effective than the other? In order to support your answer produce various statistical outputs such as descriptive statistics, graphical summaries, boxplots and perform a t-test for equality of means.
