1. According to my Fitbit, during winter quarter of 2020 (before the COVID-19 shutdown) from January 6, 2020, to March 15, 2020 (n₁ = 10 weeks), I averaged 89,054 steps per week with a standard deviation of 8,015.2 steps per week. So far this quarter, from September 6 through October 17, (n₂ = 6 weeks), I averaged 95,350.7 steps per week with a standard deviation of 7,994.6 steps per week.
   1. Conduct a two-sided test of the equality of variances for these two time periods at the = .05 level. Be sure to clearly state the null and alternative hypotheses.
   2. Conduct a one-sided test of the equality of means for these two time periods at the = .05 level. Be sure to clearly state the null and alternative hypotheses.
   3. Is the increase in my weekly walking activity this quarter compared to the last time I taught classes in person (winter quarter 2020) statistically significant?
