The work week for adults in the US that work full time is normally distributed with a mean of 47 hours. A newly hired engineer at a start-up company believes that employees at start-up companies work more on average then most working adults in the US. She asks 12 engineering friends at start-ups for the lengths in hours of their work week. Their responses are shown in the table below. Test the claim using a 1% level of significance. Give answer to at least 4 decimal places. Hours 45 50 60 50 48 61 54 49 50 48 55 50 (a) Determine the null and alternative hypotheses? Hn: Select an answer hours H1: Select an answer v? hours (b) Determine the test statistic ? (c) Determine the p-value. p-value = %3D (d) Make a decision. O Accept the alternative hypotheis O Accept the null hypothesis O Do not reject the null hypothesis O Reject the null hypothesis
