Here is the headline of an MPR news story, "MPR News/Star Tribune poll: 56 percent approve of Walz performance" Tim Pugmire | MPR News Feb 25, 2020. This story is from before the current COVID-19 crisis and we don't know how much opinions might have changed recently. A new MPR News/Star Tribune Minnesota Poll shows 56 percent of those surveyed said they approve of his job performance, 25 percent disapprove and 19 percent are unsure. The poll of 800 registered voters was conducted by Mason-Dixon Polling and Strategy from Feb. 17-19. There were at least six other questions asked in the poll, ranging from questions on spending priorities to questions on mining and marijuana legalization. Since there are many questions asked in the poll, we don't construct several confidence interval estimates for each proportion, we calculate the sample proportions and report one margin of error for the entire poll or survey.

In light of evidence about how COVID-19 spreads, the CDC recommends that people wear a cloth facemask to cover their nose and mouth in the community setting. The following is adapted from the National Panel Study of COVID-19 by Vargas et al.

During the Covid-19 pandemic, working from home has become the norm. Because of this, many households face an increasing monthly electricity bill. Mr. Tan is a research student at the Singapore University of Social Sciences, and his research focus is to examine the impact of Covid-19 on household electricity consumption. He hypothesised that the average monthly electricity bill in a household has increased more than $5 during the Covid-19 pandemic. In order to test his hypothesis, he collected the electricity bill data in 50 households in May 2020 when Singapore was during the circuit breaker period. Mr. Tan also found that the mean and standard deviation of electricity bill in a household in May 2019 are $26 and $7, respectively. In order to study the impact of Covid-19 on household electricity consumption, Mr. Tan intends to make a comparison of the average electricity bills in May 2019 and May 2020 in his analysis. Question 1. Apply an appropriate hypothesis test to determine if the…

Governor Andy Beshear stated that COVID-19 is disproportionately affecting the AfricanAmerican community in Kentucky. As of April 21, there are 144 deaths from COVID-19 where the race of the patient is known, and of those 20 are African-American. AfricanAmericans make up 8% of the population of Kentucky overall. Does this information indicate that African-Americans in Kentucky are dying from COVID-19 at a disproportionate rate? Use an α = 0.05 significance level to test this claim.
