Researchers conducted a study to examine the association of clinical factors at birth with sudden infant death syndrome (SIDS) (
Platt et al., 2000). The researchers randomly sampled the medical records of infants who died of SIDS from a large database. The study found 50 infants who required resuscitation at birth in 321 medical records, which produced a 90% confidence interval of 0.08 ± 0.02. What can the researchers conclude about this confidence interval?
Researchers are________ certain that the interval (0.06,0.10) contains the proportion of 10% 90% 95 % 5% Adapted from Platt, M Archives ofDisease in' ning P. J; et al. Clinical Comparison Of SIDS And Explained Sudden Infant Deaths: How Healthy And How Normal?
Researchers are 90% certain that the interval (0.06,0.10) contains the proportion.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
90% confidence interval of 0.08 ± 0.02.
Thus:
Researchers are 90% certain that the interval (0.06,0.10) contains the proportion.
