best point estimate for 0.678>p>0.788 with a 95% confidence interval

Does the confidence interval not change for population proportion vs sample proportion

A flu shot is administered during flu season. We look at the effect of the shot on individuals who received the shot versus those who did not. In a sample of 100 patients that received the flu shot, the average recovery time after being infected with the flu was 4 days with a standard deviation of 1 day. What is a 95% confidence interval for the population average recovery time? O (3.99.4.01) (3.80, 4.20)

Assume the temperature inside a growth chamber fluctuates randomly, and you would like to estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures: 82.1 87.1 84.6 81.3 81.8 86.1 82.3 86.7 84.6 Please construct a 90% confidence interval. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place.Confidence interval =   Express the same answer as a tri-linear inequality one decimal place. < x¯ <   Express the same answer using the point estimate and margin of error. Give your answers to one decimal place. x¯ = ±

In a Time/CNN survey, 24% of 205 single women said that they “definitely want to get married.” In the same survey, 27% of 260 men gave that same response. 1. Construct a 99% confidence interval estimate of the difference between the proportion of single women and single men who definitely want to get married.   2. Is there a gender gap on this issue? How do you know?
