Construct a 95% and 99% confidence interval of the age of adults with at most 3 vaccine shots. Compare the marginsof error for intervals. Base from your answers, make an inference in one or two sentences only.
A random sample from a population of adults consists of 67 men and 43 women. (a) Give a 95% confidence interval for the proportion of men in the population. (b) Interpret that confidence interval.
Which of the following statement(s) about confidence intervals are correct? 1) There is no relationship between sample size and confidence interval's width 2) the smaller the sample size, the wider the confidence interval. 3) The higher the confidence level, The narrower the confidence interval. 4) The higher the confidence level, The wider the confidence interval. 5) The larger the sample size, The wider the confidence interval. 6) There is no relationship between confidence level and confidence interval's width.
Construct a 95% confidence interval for p1 - p2 for a survey that finds 30% of 240 males and 41% of 200 females are opposed to the death penalty. Group of answer choices a.(-0.200, -0.021) b.(-1.532, 1.342) c.(-1.324, 1.512) d.(-0.561, 0.651)
The full question for part B is written down below. (b) The 90% confidence interval is (__,__). It does/does not seem likely that the population mean could be within 8% of the sample mean because 8% off from the sample mean would fall outside/inside the confidence interval. It does not/does seem likely that the population mean could be within 9% of the sample mean because 9% off from the sample mean would fall outside/inside the confidence interval.
What is the correct interpretation for a 95% confidence interval of the population mean μ? The probability that the population mean is in the interval is 5%. In the long run, 95% of the intervals created will contain the population mean. There is a 5% chance that the sample mean will be in the interval. 95% of the population has a value in the confidence interval.

A survey conducted on a certain website indicated that 44.7% of the people visiting this website consider the color red rather irritating and want the website to use it as little as possible. The survey had a margin of error of 4.8% with a 95% confidence level. What does this margin of error tell you about the percentage of people visiting this website who do not like the color red? We can be 95% confident that somewhere between ? % and ? % of the visitors of this website do not like the color red.
a) Determine 95% and 99% confidence limits for the proportion male students who feel “wealthwas necessary for happiness.” b) Determine 95% and 99% confidence limits for the proportion female students who feel “wealthwas necessary for happiness.” c) Determine 95% and 99% confidence limits for the difference in proportions between male students and female students who feel “wealth was necessary for happiness.” I have only posted three subparts as you allow only three subparts of question.

Explain what "98% confidence" means in a 98% confidence interval, What does "98% confidence" mean in a 98% confidence interval? O A. If 100 different confidence intervals are constructed, each based on a different sample of sizen from the same population, then we expect 98 of the intervals to include the parameter and 2 to not include the parameter. O B. The probability that the value of the parameter lies between the lower and upper bounds of the interval is 98%. The probability that it does not is 2%. O C. The confidence interval includes 98% of all possible values for the parameter. O D. The value of the parameter lies within 98% of a standard deviation of the estimate.
