Which of the following is the concept illustrated with the misentered data?OA. The procedure for constructing the confidence interval is robust. The largerthe sample size, the more resistant the mean. Therefore, the confidenceinterval is more robust.OB. The procedure for constructing the confidence interval is not robust. Thesmaller the sample size, the less resistant the mean. Therefore, theconfidence interval is more robust.OC. The procedure for constructing the confidence interval is robust. The largerthe sample size, the more resistant the mean. Therefore, the confidenceinterval is less robust.

A confidence interval was constructed to approximate a population proportion. The interval was from 12.5% to 18.5%. The sample proportion that was used to construct this interval was 15.5%. O False O True
Which is TRUE about a 99% confidence interval based on a given sample? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. The interval contains 99% of the population. a The interval is wider than a 95% confidence interval would be. The interval is wider than a 100% confidence interval would be. d Results from 99% of all samples will lie in this interval.
Which one of the following statements about confidence intervals is false? Given the same sample of data, a 99% confidence interval will be wider than a 95% confidence interval. The size of the population affects the width of a confidence interval. The sample statistic determines the center of the confidence interval. The value of z* affects the width of a confidence interval. The general format of a confidence interval is “sample statistic ± margin of error.”

Suppose a 90% confidence interval estimate mean is (25.2, 43.4). Now, using the same exact information, you compute a 95% confidence interval. Which of the following statements is correct? O The 95% confidence interval is longer. The answer can't be determined from the information given. The intervals have the same lengths The 95% confidence interval is shorter
You are interested in constructing a 95% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 409 randomly selected caterpillars observed, 58 lived to become butterflies. Round answers to 4 decimal places where possible. a. With 95% confidence the proportion of all caterpillars that lived to become a butterfly is between _________ and _________. b. If many groups of 409 randomly selected caterpillars were observed, then a different confidence interval would be produced from each group. About _________ percent of these confidence intervals will contain the true population proportion of caterpillars that become butterflies and about ____________ percent will not contain the true population proportion.
How do I solve this?

Choose the correct answer below. A. With 90% confidence. it can be said that the population mean price lies in the first interval. With 95% confidence, it can be said that the population mean price lies in the second interval. The 95% confidence interval is narrower than the on% B. With 90% confidence. it can be said that the population mean price lies in the first interval. With 95% confidence, it can be said that the population mean price lies in the second interval. The 95% confidence interval is wider than the 90% C. With 90% confidence, it can be said that the sample mean price lies in the first interval. With 95% confidence, it can be said that the sample mean price…
A survey asked, "How many tattoos do you currently have on your body?" Of the 1241 males surveyed, 182 responded that they had at least one tattoo. Of the 1047 females surveyed, 139 responded that they had at least one tattoo. Construct a 99% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. P1 Let p, represent the proportion of males with tattoos and p, represent the proportion of females with tattoos. Find the 99% confidence interval for p, - p2. The lower bound is The upper bound is (Round to three decimal places as needed.)
