To create a confidence interval from a bootstrap distribution using percentiles, we keep the middle values and chop off a certain percent from each tail. Indicate what percent of values must be chopped off from each tail for a 99% confidence interval:

Use the bootstrap distribution for a sample proportion above to estimate a 95% confidence interval. Give your answers to 2 decimal places (2dp).Lower Limit: Answer 1 Question 16 Upper Limit: Answer 2 Question 16Give the symbol for the parameter being estimated in this case: Answer 3 Question 16

Use the given data to construct a 99.5% confidence interval for the population proportion p.=x52,  =n71Round the answer to at least three decimal places.Theconfidenceintervalis, .

A researcher wishes to construct a 95% confidence interval for a population mean. She selects a simple random sample of size 8 from the population. The population is normally distributed and σ is unknown. When constructing the confidence interval estimate, the researcher uses the distribution value from the normal distribution (in Minitab). The confidence level of her resulting confidence interval estimate will beGroup of answer choicesExactly 95%Greater than 95%Less than 90%Exactly 90%Less than 95% but greater than 90%.

Let’s say you wish to construct a sampling distribution of sample size 100 for the proportion of people that voted for AAP. Suppose the population standard deviation is known to be 0.7, what is the interval in which the mean of the sampling distribution will belong at a 90% confidence level?(0.485, 0.675) (0.572, 0.588)(0.465, 0.695)(0.503, 0.657)

If n=30, 𝑥¯(x-bar)=35, and s=7, construct a confidence interval at a 99% confidence level. Assume the data came from a normally distributed population.Give your answers to one decimal place. < 𝜇 <
