  1. Conduct a 95% hypothesis test for your slope coefficient (a t-test). Interpret, in words and with numerical evidence, the conclusion of that hypothesis test.
  2. Conduct a 95% hypothesis test for your model (a F-test). Interpret, in words and with numerical evidence, the conclusion of this hypothesis test.

Please conduct a Hypothesis test in the following scenario to determine if the population slope is statistically significant. State the appropriate test statistic, the critical values, and whether or not you can reject a null hypothesis that the population slope is zero. Use a 1% significance level. Suppose that you collected data to determine the relationship between the amount of time a person spends online as an independent variable and the amount of money a person spends online as the...

On your first day on the job, your boss asks you to conduct a hypothesis test about the mean dwell time of a new type of UAV. Before you arrived, an experiment was conducted on n= 5 UAVs (all of the new type) resulting in a sample mean dwell time of y-bar= 9.4 ℎours. The goal is to conclusively demonstrate, if possible, that the data supports the manufacturer’s claim that the mean dwell time is greater than 10 hours. Given...
