Hospital Size Time to Defibrillation

< or equal to 2 minutes >2 minutes

Small (<250 beds) 1124    576

medium (250-499 beds) 2178 886

Large (>500 beds) 1387    565

One research question that could be posed using the available data: " is there an advantage to being at a larger hospital for patients suffering cardiac arrest?" Determine a method that would be appropriate for answering this research questions. Using Statcrunch and the available data, perform the statistical procedure deemed appropriate. In or to two paragraphs explain: 1) what method was used to answer the research questions

2) the reasoning for using that particular method

3) the relevant findings interpreting them in the context of the research questions.

CRITICAL VALUE:

degree of freedom (df) = 2

test statistics ( 14.7935) is greater than critical value (5.991)

so we reject null hypothesis ( H 0 ) ,hence there is advantage to being at larger hospital

NOTE: if you have any doubts please comment and free to ask

A small community college claims that their average class size is equal to 35 students. This claim is being tested with a level of significance equal to 0.02 using the following sample of class sizes: 42, 28, 36, 47, 35, 41, 33, 30, 39, and 48. Assume class sizes are normally distributed. (NOTE: We need to assume that class sizes are normally distributed in order to use the t distribution because the sample size n=10 < 25, and the Central...
