Assume that a sample is used to estimate a population proportion p. Find the 99.9% confidence interval for a sample of size 269 with 52% successes. Enter your answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places. < p < Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places. instructor
105 students at a college were asked whether they had completed their required English 101 course, and 62 students said "yes". Construct the 90% confidence interval for the proportion of students at the college who have completed their required English 101 course. Enter your answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places.
We wish to estimate what percent of adult residents in a certain county are parents. Out of 600 adult residents sampled, 150 had kids. Based on this, construct a 90% confidence interval for the proportion p of adult residents who are parents in this county. Express your answer in tri-inequality form. Give your answers as decimals, to three places. p Express the same answer using the point estimate and margin of error. Give your answers as decimals, to three places. K P= Submit Question
A question I have is the effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 27.7 for a sample of size 912 and a standard deviation of 21.3.Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 90% confidence level).Enter your answer as a tri-linear inequality accurate to one decimal place (because the sample statistics are reported accurate to one decimal place). < μ <
The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 32.3 for a sample of size 26 and standard deviation 15.7. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 98% confidence level). Assume the data is from a normally distributed population.

claim: Most adults would not erase all of their personal information online if they could. A software firm survey of 585 randomly selected adults showed that 49.3% of them would erase all of their personal information online if they could. Make a subjective estimate to decide whether the results are significantly low or significantly high, then state a conclusion about the original claim.

A certain statistics instructor participates in triathlons. The accompanying table lists times (in minutes and seconds) he recorded while riding a bicycle for five laps through each mile of a 3-mile loop. Use a 0.05 significance level to test the claim that it takes the same time to ride each of the miles. Does one of the miles appear to have a hill? Click the icon to view the data table of the riding times. Determine the null and alternative hypotheses. Ho: H₁: Find the F test statistic. F = Find the P-value using the F test statistic. P-value = What is the conclusion for this hypothesis test? (Round to four decimal places as needed.) (Round to four decimal places as needed.) C O A. Fail to reject Ho. There is insufficient evidence to warrant rejection of the claim that the three different miles have the same mean ride time. O B. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that the three different miles have the same mean ride time. O C. Reject…
