Answer #1

(a)

the prevalence rate of AIDS in the U.S. in 2005.= number of persons living with AIDS in the United States /  population of the U.S. in 2005

= ( 397,582. +  40,608 )/ 296,410,404

= 438190/ 296,410,404

= 0.001478

= 0.1478%

So,

Answer is:

0.1478%

(b)

the incidence rate of AIDS in the U.S. in 2005.= number of new cases of AIDS were reported in the U.S. /  population of the U.S. in 2005

= 40,608 / 296,410,404

= 0.001370

= 0.0137%

So,

Answer is:

0.0137%

       There were 53 diagnoses of new cases of Multiple Sclerosis (MS) in Tasmania in 2018, increasing the total number of Tasmanians living with MS to 2550. The population of Tasmania is 500,000 people. Calculate the incidence and prevalence of MS in Tasmania per 100,000 people per year. incidence of MS prevalence of MS iii. Improvements treatment mean people are now living longer with MS. Explain how this will change the incidence and prevalence of MS in Australia.

In 1989, research scientists published a model for predicting the cumulative number of AIDS cases reported in the United States: a(t) = 155((t − 1980)/10)^3 (thousands) where t is the year. This paper was considered a "relief," since there was a fear the correct model would be of exponential type. Use the two data points predicted by the research model a(t) for the years 1989 and 1995 to construct a new exponential model b(t) for the number of cumulative AIDS...

A.) Now the population is all senior living facilities in the United States. It is conjectured that the mean number of positive COVID-19 cases per 100 residents is 40, and of interest is to test the conjecture versus the alternative that the mean number of positive COVID-19 cases per 100 residents is different from 40. State the appropriate null and alternative hypotheses that should be tested. B.) Consider the information and hypotheses specified in the above part a.. A simple...

In Brazil, extensive Zika testing began last year and is ongoing. In total, an estimated 1.48 million people have tested positive for Zika. This total counts all those who tested positive during the very first tests, and continues to count all additional cases that have occurred since. The total population of Brazil is 208 million. With these data, we can calculate which of the following measures of disease: Cumulative incidence Incidence rate Point prevalence Period prevalence

According to the U.S. Census Bureau, 11% of children in the United States lived with at least one grandparent in 2009 (USA TODAY, June 30, 2011). Suppose that in a recent sample of 1570 children, 239 were found to be living with at least one grandparent. At a 10% significance level, can you conclude that the proportion of all children in the United States who currently live with at least one grandparent is higher than 11%? Use both the p-value...
