Use the sample data and confidence level given below to complete parts​ (a) through​ (d).   A drug is used to help prevent blood clots in certain patients. In clinical​ trials, among 4321patients treated with the​ drug, 148 developed the adverse reaction of nausea. Construct a 95​% confidence interval for the proportion of adverse reactions. ​a) Find the best point estimate of the population proportion p. ______________ (Round to three decimal) b. identify the value of the margin of error E E=______________   c. construct the confidence interval _____<p<________   d. write a statement that correctly interprets the confidence interval.

Use the given degree of confidence and sample data to construct a confidence interval for the population mean u. Round your final answers to the nearest hundredth. Test scores: n = 104, x = 95.3, o = 6.5; 99% confidence You will need to calculate the margin of error, followed by the lower and upper end of the confidence interval. Margin of Error: choose your answer.. Confidence Interval: choose your answer... レ choose your answer...

Use the given confidence interval to find the margin of error and the sample proportion.   ​(0.740​,0.766​)         E=enter your response here ​(Type an integer or a​ decimal.)
