For a project, a student randomly sampled 182 other students at utsa to determine if the majority of students were in favor of a proposal to sell alcohol at chili’s. he found that 75 were in favor of the proposal. use this information to calculate a 95% confidence interval to estimate the proportion of utsa students that are in favor of a proposal to sell alcohol at chili’s.
what is the point estimate of the proportion (p)qr1enlsr1vwesi0ojibwz6qqxppzvl2m 0y7ti92a in the population of utsa students that are in favor of a proposal to sell alcohol at chili’s?

a certain filling machine has a true population standard deviation σ = 0.228 ounces when used to fill catsup bottles. a random sample of 36 "6 ounce" bottles of catsup was selected from the output from this machine and the sample mean was 6.018 ounces. find a 90% confidence interval estimate for the true mean fills of catsup from this machine.
what is the point estimate (x) 87zkwhucssuvork5cyii=of the true mean fill of catsup from this machine?
calculate a 90% confidence interval for the true mean fills of catsup from this machine.
calculate a 95% confidence interval for the true mean fills of catsup from this machine.
ten randomly selected shut-ins were each asked to list how many hours of television they watched per week. the results are: 82 66 90 84 75 88 80 94 110 91. the sample mean standard deviation is 11.84.
what is the point estimate (x) 87zkwhucssuvork5cyii=of for the true mean number of hours of television watched per week by shut-ins?
