Aresearcher is conducting a study to learn about the difference in dog walking habits among dog owners of rural areas versus urban areas. suppose the researcher calculates a 95% confidence interval for the difference in population mean number of hours per week that dog owners in rural areas (group 1) spend walking their dogs and the population mean number of hours per week that dog owners in urban areas spend walking their dogs (group 2) and comes up with the interval (-0.15 hrs, 0.45 hrs).is the following statement true of false? a correct interpretation of the confidence level is “if we were to repeat this sampling procedure many times sing the same sample size and form the same populations, and each time constructed a 95% confidence interval, we would expect 95% of the resulting 95% confidence intervals to contain the difference in the sample mean number of hours per week spend walking their dogs for the population of owners in rural areas versus the population of owners in urban areas.
