A recent study states that moonlight can affect the survival rate of new plants. It reported that 26 of 50 plants that were shielded from moonlight survived and 19 of 65 plants left unshielded survived. Choose the 95% confidence interval that represents the difference between the proportions of shielded and unshielded new plants that survive.
Answers: 2
represent the real population proportion of shielded survived
represent the estimated proportion of shielded survived
is the sample size required of shielded survived
represent the real population proportion for unshielded survived
represent the estimated proportion for unshielded survived
is the sample size required for unshielded survived
represent the critical value for the margin of error
and 
, with that value we can find the quantile required for the interval in the normal standard distribution.

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
