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.
- Clearly label a sketch of the sampling distribution with appropriate shading.
- 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?

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...
