A report from the U.S. Department of Agriculture shows that the mean American consumption of carbonated beverages per year is greater than 52 gallons. A random sample of 30 Americans yielded a sample mean of 69 gallons. Assume that the population standard deviation is 20 gallons, and the consumption of carbonated beverages per year follows a normal distribution. Calculate a 95% confidence interval, and write it in a complete sentence related to the scenario.

Accounting:

At the end of 2019, BETA Ltd, in order to compile the 2020 budget, gives the following info: - Product P1: Stock (in units) 31/12/2019: 7.000 - Product P2: Stock (in units) 31/12/2019 9.000 Company predicts to sell 20.000 EUR of P1 with price EUR 10 and EUR 25.000 of P2 with price EUR 12. Also, the final stock of P1 is expected to be 30% of its sales in units and the final stock of P2 20% of its sales in units. Concerning raw materials, the stock in units on 31/12/2019 is for Material M1 8.000 in units and for Material M2 12.000 in units. Also final stock for M1 is expected to be 10% of its use and for M2 20% of its use. Finally, note that for the production of P1 , 1 M1 and 3 M2 are needed and for the production of P2, 4M1 and 2 M2 are needed. The following are needed: a. The production in units for P1 and P2. b. Assuming that raw material M1 is bought EUR 4 per kilo and raw material M2 EUR 2 per kilo, find the cost of the required purchases of M1 and M2. c. Assuming that the cost of raw material M1 is EUR 4 per kilo and the cost of raw material M2 EUR 3 per kilo, direct labour 70.000, cost of electricity at head office 30.000, indirect materials 45.000 and the rest various factory costs 95.000 , find the direct (first ) cost of the company.

How is the coronavirus pandemic affecting wildlife? With fewer cars on the roads, and with parks and wildlife areas closed to the public for several weeks, the Stay-at-Home Order (shelter in place) likely affected some animal populations in urban areas.

describe two examples of how animals have been affected.
Make sure to include the type of animal affected, and how they are affected. If you have directly witnessed affected wildlife, you may use that as one example.
