If you have two samples with the same sample mean but differentsample sizes, what would you expect regarding their confidenceintervals? Since the samples are from the same population there thepopulation standard deviation is the same for both.O The one with the larger sample size will have a wider confidence interval.The confidence intervals will be the same.O The one with the larger sample size will be shifted to the right.The one with the smaller sample size will have a wider confidence interval.The one with the smaller sample size will be shifted to the right.Mli

From the given information we find the correct Option regarding confidence interval.

Answered: f you have two samples with the same…

You are interested in constructing a 99% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 441 randomly selected caterpillars observed, 59 lived to become butterflies. Round answers to 4 decimal places where possible. a. With 99% confidence the proportion of all caterpillars that lived to become a butterfly is between and b. If many groups of 441 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.
A statistics practitioner took a random sample of 57 observations from a population whose standard deviation is 25 and computed the sample mean to be 103. Note: For each confidence interval, enter your answer in the form (LCL, UCL). You must include the parentheses and the comma between the confidence limits. A. Estimate the population mean with 95% confidence. Confidence Interval = B. Estimate the population mean with 95% confidence, changing the population standard deviation to 58; Confidence Interval = C. Estimate the population mean with 95% confidence, changing the population standard deviation to 7; Confidence Interval =

You are interested in constructing a 90% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 377 randomly selected caterpillars observed, 42 lived to become butterflies. Round answers to 4 decimal places where possible. a. With 90% confidence the proportion of all caterpillars that lived to become a butterfly is between and b. If many groups of 377 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.
Suppose that the coach from Question 3 decides he wants to be more confident. The coach uses the same sample data as before, but recalculates the confidence interval using a 99% confidence level. How will increasing the confidence level from 95% to 99% affect the confidence interval? A B с D It is impossible to say without seeing the sample data. Increasing the confidence will increase the margin of error resulting in a wider interval. Increasing the confidence will decrease the margin of error resulting in a narrower interval. Increasing the confidence will have no effect on the interval.

Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
Which one of the following statements is true? The sample proportion is a parameter. A confidence interval is computed in order to estimate an unknown sample statistic. The margin of error is affected by the size of the sample proportion. If you construct a confidence interval for a population proportion and the interval ends up being from 0.48 to 0.59, this means the population proportion is definitely larger than 0.50. If a 95% confidence interval is given as 0.32 to 0.46, this means the sample proportion must be 0.38.
suppose that you take 1000 simple random samples from a population and that, for each sample, you obtain a 95% confidence interval for an unknown parameter. Approximately how many of those confidence intervals will continue the value of the unknown parameter?
There are several sections of Statistics; some in the morning and some in the afternoon. We randomly select n1 40 from the morning section and 44 from the afternoon section. The averages n2 of their scores are X1 76.3 for the morning section and X, = 71.9 for the afternoon section. The known standard deviations of their scores are 01 12.05 for the morning section and 02 13.06 for the afternoon section. Test the claim that the average for all students in the morning and afternoon section is the same. Use a a = 0.05 significance level. a. What is the negative critical region? Give your answer to two decimal places. z c. What is the test statistic? Give your answer to two decimal places. z = d. Do we reject or fail to reject the null hypothesis?
