At the time she was hired as a server at the Grumney Family Restaurant, Beth Brigden was told, “You can average $88 a day in tips.” Assume the population of daily tips is normally distributed with a standard deviation of $2.50. Over the first 50 days she was employed at the restaurant, the mean daily amount of her tips was $89.93. At the 0.10 significance level, can Ms. Brigden conclude that her daily tips average more than $88?a.State the null hypothesis and the alternate hypothesis.

Math Project/Worksheet
ATTACHED Objective: This project is intended to give you practice with calculating income from investments and predicting monetary needs based on future and current expenditures. You will identify professions and locations that appeal to you so that you may begin thinking about what may affect future decisions. Make the following assumption: You will graduate this Spring and get your preferred job immediately upon graduation. Be sure to show all calculations when asked.1. State the profession that you intend or would like to pursue and where you would like to live. Explain something about why you selected your chosen profession and desired location.2. Research potential starting salaries and possible house prices for your choices in your desired location and provide them. Include your citations for the values and any assumptions that you are making about your choices. 3. Research what the state and federal income taxes are for the state in which you want to live. Keep in mind that not all states have a state income tax. Based on your research, what will your salary be after taxes? Show calculations.4. Let’s assume that housing prices will remain relatively stable. You will need 20% for a down payment for your chosen house from Step 2. You plan on moving and purchasing the house in 5 years from now. How much would you need to save every month in order to have the down payment? Assume an APR of 5%. Show calculations.5. If you put away $100 a month from after graduation until retirement (age 65) in an investment account with an APR of 3.5% how much will you have to retire on? Show calculations. Show calculations on a separate sheet.6. Recreate the table on page 2 (showing monthly amounts) and calculate your monthly budget and cash flow based on the salary you found in Step 2. You can add or eliminate as needed.
