0 Question 6 v You collect 45 sample data values to build a confidence interval for a population mean. You put the data in your calculator, press 1-Varstats, and get this output: E = 117.5 SI 13 or: 2 12854744044299 Select the correct statement: ""1? Use a Z-interval since it 23 30 3":3' Use a T-Interval with .5 since the data came from a sample "'3' Use a Z-lnterval, since the calculator gave you 0' '5'} Use a T-Interval with 0' since that will be more accurate 0 Question 7' v You are building a CI for a population mean. The sample statistics are as follows: it = 45, 5E = 78.6, s = 12.5 Select the correct statement: '37:? Build a T-lnterval since the population standard deviation is not known '73' Build a Z interval since you know the population standard deviation ""3 Build a T-lnterval since you know the population standard deviation 13:3 Build a Z-lnterval since n a 30 Question 9
