Ht: to test if there is sufficient evidence to conclude that the population proportion is sig. different than expected. Parameter of interest: difference in population proportion p. Ci: to estimate the difference in the population proportions. Ht: to see if there is a sig. difference between the two populations. Parameter of interest: value of the population mean . Ht: to see if there is a sig. difference between the sample population mean and the expected population mean. Parameter of interest: population mean difference d. Ci: to estimate the population mean difference. Ht: to determine if there is a sig. difference between the sampled population mean difference, and the expected population mean difference. Parameter of interest: difference in population mean 1 - 2.
