You're considering going to graduate school, and you would like to know how many people would recommend it. You talk to 29 people, and 7 recommend it. Construct a 96% confidence interval for p, the proportion of people that recommend you go to graduate school. What is the lower bound of this interval?

A research survey is commissioned to estimate the proportion of UK people who have traveled to France by taking Eurostar. The survey is told that the estimate must not differ from the true proportion by more than 3% with a confidence level of 95%. How large a sample should be taken? How about at 99% confidence?

Determine whether the statement below makes sense or does not make sense. Explain clearly. Based on our sample, the 95% confidence interval for the mean amount of television watched by adults in a nation is 2.9 to 4.3 hours per day. Therefore, there is 95% chance that the mean for all adults in the nation will fall somewhere in this range and a 5% chance that it will not. C Choose the correct answer below. O A. The statement makes sense. There is 5% probability that the confidence interval limits do not contain the true value of the sample mean, so the probability it does not contain the true value of the population mean is also 5%. O B. The statement does not make sense. The population mean is a fixed constant that either falls within the confidence interval or it does not. There is no probability associated with this. O C. The statement does not make sense. The probability the population mean is greater than the upper limit is 5% and the probability it is less than the lower limit is…
