Through March 16th of this year, 12% of patients in the United States who had contracted COVID-19 were hospitalized (Centers for Disease Control). In Orange County, Florida, as of April 8, 2020, out of 931 confirmed COVID-19 cases, there were 129 hospitalizations (The Orange County Register). Use this sample information to conduct a test of significance to determine whether the rate of hospitalization due to COVID-19 in Orange County is greater than the rate of hospitalization in the United States population.

  1. Clearly label a sketch of the sampling distribution with appropriate shading.
  2. Test this hypothesis using a significance level of α = 1%. Include all of your calculations.

In the United States in 2007, the proportion of adults age 21-24 who had no medical insurance was 28.1%. A survey of 75 recent college graduates in this age range finds that 30 of them are without insurance. Does this support a difference from the nationwide? • Perform a two-sided significance test in R for a proportion, following the procedure of seven steps in the lecture note (choose a significance level of 0.05). • Use the related function in R...

If 2 million people had chronic hepatitis C in the United States last year, and of these 120,000 received treatment that cured them of hepatitis C and 80,000 died. What is the minimum number of new hepatitis C cases that would have to have been reported last year in order for you to conclude that prevalence is increasing?

A professor states that in the United States the proportion of college students who own iPhones is .66. She then splits the class into two groups: Group 1 with students whose last name begins with A-K and Group 2 with students whose last name begins with L-Z. She then asks each group to count how many in that group own iPhones and to calculate the group proportion of iPhone ownership. For Group 1 the proportion is p1 and for Group...
