Abstract:
Allele frequencies of 14 STR loci (D13S317, D16S539, D2S1338, vWA, TPOX, D18S51, D5S818, FGA, D8S1179, D21S11, D7S820, CSF1PO, TH01 and D3S1358) observed in the population of Malta are being reported. Polymerase chain reaction (PCR) amplification using the AmpFl STR Identifiler kit was performed in a random sample of 157 subjects (314 chromosomes). Markers D2S1338, D18S51 and FGA had the highest power of discrimination (PD) values while TPOX was the least informative marker. Allele frequencies observed in the Maltese population were also compared with those of other populations from the Mediterranean region, Europe and Africa. Our data is useful for anthropological and other comparative studies of populations and is powerful for forensic and paternity testing in the Maltese islands.

Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
