Can I please get some help with this questions,thank you!

A teacher is interested in what proportion of De Anza statistics students submit their homework on time. She randomly surveys 40 students and nds that 30 of them submit their homework on time. The point estimate for the proportion of De Anza statistics students that submit their homework on time is: {3040 C330 {3030 c>o75 A teacher is interested in what proportion of De Anza statistics students submit their homework on time. She randomly surveys 40 students and finds that 30 of them submit their homework on time. The error bound for a 95% confidence interval for the true proportion of De Anza statistics students who submit their homework on time is: 0.1126 0.2684 0.2252 O 0.1342A teacher is interested in what proportion of De Anza statistics students submit their homework on time. She randomly surveys 40 students and finds that 30 of them submit their homework on time. For the confidence interval, if we repeated the study keeping the same level of confidence (95%) and increased the sample size, what would we expect to happen? O The interval must contain the true proportion. O The error bound would increase. O The error bound would decrease. The error bound would not change.A bag of cookies contains 6 chocolate cookies, 5 sugar cookies, and 1 oatmeal cookie. Two cookies are selected at random, one after another, and eaten.
