3. What is the number of degrees of freedom that you would use to calculate Add a C the 95% confidence interval for the population mean number of benefits distributed? Degrees of freedom= 48 4. What is the value of the upper bound of the 95% confidence interval for the Med population mean percent of people who are positive for a disease? Assume Save the relevant critical value=D2. Upper bound= 5. What is the value of the lower bound of the 95% confidence interval for the population mean percent of people who are positive for a disease? Assume the relevant critical value=2. Lower bound= 6. Someone claims that the population mean percent of people who are positive for a disease is 0.05. Perform a two-sided hypothesis test of this claim at the 1% significance level. I. What is the relevant t-statistic? Round your answer to two decimal places if necessary. t-statistic= II. Assume the relevant p-value is 0.05. What is your conclusion? at the significance level. (Fill in the blanks with two of the options A-L below. Enter only the letter (e.g. A) as your answer) MacBook Pro
