Question
**Title: Statistical Analysis of Work Hours in Start-up Companies** **Introduction:** The standard work week for full-time adults in the United States is normally distributed with a mean of 47 hours. A newly hired engineer at a start-up company proposes that employees at start-up companies tend to work more hours than the average full-time adult in the US. To investigate this, she collects data from 12 engineering friends working at various start-ups, asking for the lengths of their work weeks in hours. **Data Collection:** The recorded work hours are as follows: | Hours | |-------| | 49 | | 50 | | 52 | | 51 | | 46 | | 61 | | 45 | | 45 | | 50 | | 50 | | 51 | | 55 | **Objective:** The objective is to test the claim that start-up employees work more hours on average than the general US population of full-time workers. This will be tested using a 5% level of significance. **Methods:** - Conduct a hypothesis test to compare the sample mean to the known population mean. - Use a significance level of 0.05 to determine if the observed sample provides enough evidence to support the claim. - Calculate the sample mean and standard deviation, and perform a t-test for the mean difference. **Conclusion:** The outcome of the hypothesis test will determine whether there is statistical evidence to support the claim that start-up employees work longer hours than the average US full-time worker. (Note: The detailed statistical calculations and analysis should be included in the educational content to guide readers through the process.)
