According to my Fitbit, during winter quarter of 2020 (before the COVID-19 shutdown) from January 6, 2020, to March 15, 2020 (n = 10 weeks), I averaged 89,051.4 steps per week with a standard deviation of 8,015.2 steps per week. So far this quarter, from September 6 through October 17, (n = 6 weeks), I averaged 95,350.7 steps per week with a standard deviation of 7,994.6 steps per week. a. 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. Conduct a one-sided test of the equality of means for these two time b. periods at the 05 level. Be sure to clearly state the null and alternative hypotheses. 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?
