Find the minimum sample size you should use to assure that your estimate of p will be within the required margin of error around the population p. Margin of error: 0.009; confidence level: 99%; p and q are unknown 72 20,465 185 20,464 QUESTION 5 Solve the problem. Find the value of -Za/2 that corresponds to a level of confidence of 96.16 percent. 0.0192 2.07 -2.07 -1.77 1 points Save Answer QUESTION 6 1 points Save Answer Determine whether the given conditions justify using the margin of error E = Za/2 on when finding a confidence interval estimate of the population mean u. The sample size is n = 8, σ is not known, and the original population is normally distributed. No Yes QUESTION 7 Use the given degree of confidence and sample data to construct a confidence interval for the population mean μ. Assume that the population has a normal distribution. n = 10, x 9.8, 52.4, 95 percent 8.11<<11.49 8.41 << 11.19 1 points Save Answer
