A cross-sectional study is conducted to investigate cardiovascular disease (CVD) risk factors among a sample of patients seeking medical care at one ofthree local hospitals. A total of 1100 patients are enrolled.

Question

The superintendent of Hospital 2 performed the Goodness of Fit Test to test whether 25% of the patients go to Hospital 1, 20% of the patients go to Hospital 2 and 55% of the patients go to Hospital 3.

Given: The superintendent found that the p-value for the test is 0.004.
Let: p1= be the proportion of patients at Hospital 1
p2= be the proportion of patients at Hospital 2
p3= be the proportion of patients at Hospital 3

a) give the null hypothesis

b) calculate the value of the test statistic

c) the smallest level of significance, at which H0 may be rejected is?
