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
Please do not give solution in image format thanku Velvetleaf is a particularly annoying weed in cornfields. It produces lots of seeds, and the seeds wait in the soil for years until conditions are right. How many seeds do velvetleaf plants produce? (Use 99% confidence). Here are counts from 28 plants that came up in a cornfield when no herbicide was used: 2450 2504 2114 1110 2137 8015 1623 1531 2008 1716 721 863 1136 2819 1911 2101 1051 218 1711 164 2228 363 5973 1050 1961 1809 130 880 from to
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.
