At certain points during the COVID-19 pandemic, many of us had no choice but to complete our work from home. For some employees, working from home was so rewarding that they found themselves wishing they could work from home indefinitely. One report, in fact, claimed that 75% of workers with jobs that could be done from home said that if they had a choice, they'd like to continue working from home all or most of the time, even when it's safe for them to work outside of their home. Believing this claimed value is too high, a researcher surveys a random sample of 945 adult employees and finds that 693 of them would like to continue working from home all or most of the time after COVID-19 restrictions ease. 1. If we want to use the above information to conduct a hypothesis test, we need to begin with two competing hypotheses. The first hypothesis is the initial claim to be tested about the population. Ho: p = 0.75. What do we call this hypothesis? 2. The second hypothesis we begin with illustrates our theory, or what we believe is actually going on in the population (i.e., the reason we are conducting the hypothesis test in the first place). Ha: p " (or greater than) sign?

5. Before we can conduct our hypothesis test, we need to determine the sample proportion. Recall that 945 employees were surveyed, and 693 of them said they would like to continue working from home all or most of the time. What will the sample proportion (or ??) be? Please compute this value below and round your answer to three decimal places. 6. To be able to conduct a hypothesis test, we will now need to compute a test statistic (using the following formula).
