The XYZ company is revisiting its policy regarding expecting its employees to check their work email outside of typical business hours. The head of Human Resources (HR) feels that checking e-mail outside of business hours could be related to their experienced stress levels. On the one hand, it could be the case that being on top-of work email will have employees worry less about their career stability and as a result they become less stressed. On the other hand, it would be the case that employees are unable to disengage from work and spend quality time with their families and as a result they become more stressed. As a result, HR sent out surveys and collected data on how frequently employees check their emails outside of typical business hours as well as their experienced stress levels. Survey questions were based on a scale from 1-7, where 1 indicates very low frequency of checking e-mails as well as low stress level (NEVER) and 7 indicates very high frequency of checking e-mails as well as high stress level (ALWAYS). The Excel file E-mail checking. xlsx has the sample data.
XYZ company would like you (as a junior business analyst) to use this sample data and answer the following questions:
Is there a relationship between e-mail checking outside of office hours and perceived stress level?

5. profit maximization and shutting down in the short run suppose that the market for polos is a competitive market. the following graph shows the daily cost curves of a firm operating in this market. 0 2 4 6 8 10 12 14 16 18 20 50 45 40 35 30 25 20 15 10 5 0 price (dollars per polo) quantity (thousands of polos) mc atc avc for each price in the following table, calculate the firm's optimal quantity of units to produce, and determine the profit or loss if it produces at that quantity, using the data from the previous graph to identify its total variable cost. assume that if the firm is indifferent between producing and shutting down, it will produce. (hint: you can select the purple points [diamond symbols] on the previous graph to see precise information on average variable cost.) price quantity total revenue fixed cost variable cost profit (dollars per polo) (polos) (dollars) (dollars) (dollars) (dollars) 12.50 135,000 27.50 135,000 45.00 135,000 if the firm shuts down, it must incur its fixed costs (fc) in the short run. in this case, the firm's fixed cost is $135,000 per day. in other words, if it shuts down, the firm would suffer losses of $135,000 per day until its fixed costs end (such as the expiration of a building lease). this firm's shutdown price—that is, the price below which it is optimal for the firm to shut down—is per polo.
