You wish to compute a 90% confidence interval for the population proportion. How large a sample should you draw to ensure that the sample proportion does not deviate from the population proportion by more than 0.07? No prior estimate for the population proportion is available. (Round the z-value to 3 decimal places.)

Use the following information for the next 2 questions. Create a confidence interval for the true population mean, given the following information. x bar (sample mean)  = 10μ (population standard deviation) = 5n (sample size) = 50α (alpha) = 0.05level of confidence = 95%
