Telecorp Inc. sells holiday greeting cards via phone solicitation. Twenty-four new salespersons were hired in January 2020. The company provides training for the first month of their employment. This year, the company decided to engage a relatively expensive training consultant on a test basis to train a random sample of 12 of their 24 new hires. The other twelve received the internal training that the company provides. Management desires more information about the value of the external trainer to decide whether it will seek to extend the agreement with the training consultant to train all the new hires. The company will conduct this test in January 2020 and again in January 2021. The company does not have a directional hypothesis ex ante (in advance) regarding the impact of the trainer since it is certainly conceivable that the external training consultant could be less effective than the in-house trainers.

Sales data from year one is shown in the EXCEL data file in the tab entitled “Telecorp Inc. Sales”.

Please complete the following:

1. Produce a table of descriptive statistics for the respective groups using the EXCEL data analysis technology.
2. Highlight on the output the means, medians, and standard deviations for the two groups.
3. Based on this initial data, what is the probability that the difference in sales between the two groups is not random and instead occurred because the external trainer had an impact on the selling ability of the sales persons that received their training from her? Please provide evidence to support your conclusion.

Let's say we are planning on adding a very large modern sign to attract customers to our marijuana and tattoo shop that we run just north of Denver. We've completed a ton of market analysis and we are fairly confident that the sign will increase sales by $50,000 per year for the first two years, and then we think it will result in an increase of $35,000 per year for the next four years. The margins we earn on our sales of marijuana is 70% and the margins we earn on our tattoos is 40%. We expect that the incremental sales resulting from the sign will be split 50-50 between marijuana products and tattoo services.

The sign will cost us $110, 000 and the company has no debt. The owners of the company expect to earn 15% on the funds they invest in the company. After six years, the sign will likely be taken down and sold for scrap to yield $5,000.
