Dog walking habits: rural versus urban dog owners

A researcher 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).

Question 4 Subquestions

4.a0.5 point(s)

Is the following statement True or False?

A correct interpretation of the confidence level is If we were to repeat this sampling procedure many times using the same sample size and from the same populations, and each time constructeda 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.

• True
• False

4.b0.5 point(s)

Is the following statement True or False?

Because more of the confidence interval is positive, the population mean number of hours per week that dog owners in rural areas spend walking their dogs is higher than the population mean number of hours per week that dog owners in urban areas spend walking their dogs.

• True
• False

4.c0.5 point(s)

Is the following statement True or False?

We estimate the difference in the population mean number of hours dog owners spend walking their dogs in rural areas versus urban areas to be 0.15 hours with a 95% margin of error of 0.30 hours.

• True
• False
