Essay

A researcher selects a random sample of 15 young adult females, all of whom were engaged to be married within the next three months. The women were given the MCS (Marriage Commitment Scale), a test with a female population mean of 25. Their scores were: 23,26,27,24,28,19,22,24,27,30,26,28,24,26,29.
-Is this sample representative of the population at large? The average sentence (in months) for homicide is 227 (Gaines & Miller, 2003). A sample of inmates from a certain prison, all of whom having been convicted of homicide, was selected and their sentences calculated. The sentences follow: 200, 225, 197. 256, 300, 158, 220, 226, 230, 215, 237, 223, and 243.
