Transcribed Image Text:An epidemiologist is worried about the prevalence of the flu in East Vancouver and the potential shortage of vaccines for the area.
She will need to provide a recommendation for how to allocate the vaccines appropriately across the city. She takes a simple
random sample of 330 people living in East Vancouver and finds that 38 have recently had the flu.
For each of the following statements, specify whether the statement is a correct interpretation of the 95% confidence interval for
the true proportion of East Vancouver residents who have recently had the flu.
A. 11.52% (38/330) of East Vancouver residents have recently had the flu. ?

B. There is a 95% probability that the true proportion of East Vancouver residents who have recently had the flu equals 38/330.
?
C. If another random sample of 330 East Vancouver residents is drawn, there is a 95% probability that the sample proportion of
East Vancouver residents who have recently had the flu equals 38/330. ?
D. If many random samples of 330 East Vancouver residents are drawn, 95% of the resulting confidence intervals will contain the
value of the true proportion of East Vancouver residents who have recently had the flu. ?
E. If many random samples of 330 East Vancouver residents are drawn, 95% of the resulting confidence intervals will contain the
value 38/330. ?
