2. An investigator predicts that dog owners in the country spend more time walking their dogsthan do dog owners in the city. The investigator gets a sample of 21 country owners and23 city owners. The mean number of hours per week that city owners spend walking theirdogs is 10.0. The standard deviation of hours spent walking the dog by city owners is 3.0.The mean number of hours' country owners spent walking their dogs per week was 15.0.The standard deviation of the number of hours spent walking the dog by owners in thecountry was 4.0. Do dog owners in the country spend more time walking their dogs thando dog owners in the city?

Given : Country Owners : n = 21 x1 = 15s1 = 4 City Owners : n = 23 x2 = 10s2 = 3

Answered: An investigator predicts that dog…

A college administrator wants to see if students in different majors tend to have differing amounts of study time. The administrator collects the following data from 15 students in Sociology, 10 students in Engineering, and 12 students in History. The Sociology majors report an average of 10 hours studies per week and a standard deviation of 3 hours. The Engineering students report an average of 15 hours per week with a standard deviation of 7 hours. The History majors report an average of 12 hours studied and a standard deviation of 4 hours. The data can be summarized as follows: Major n Mean Study Hours Standard deviation Sociology 15 10 hours 3 hours Engineering 10 15 hours 7 hours History 12 12 hours 4 hours Does this data provide evidence for the notion that students in different majors study different amounts?

A luxury furniture manufacture will make custom furniture for their customers. Pricing is based on the number of hours of skilled labor it takes to make a piece. The time it takes to make a custom couch is normally distributed with an average of 280 hours and a standard deviation of 40 hours. What percent of custom couches take 255 hours or less to make? How long would it take to build a couch that is in the 95th percentile?
Español Valley College and Elm College are two local colleges. For each college, the distribution of the ages of faculty members is clearly bell-shaped. The ages of faculty members at Valley College have a population mean of 51 years and a standard deviation of 6.3 years. The ages of faculty members at Elm College have a population mean of 56 years and a standard deviation of 4.2 years. Maria is 67 years old and a faculty member at Valley College. Salma is 40 years old and a faculty member at Elm College. (a) Find the z-scores of Maria's age as a faculty member at Valley College and Salma's age as a faculty member at Elm College. Round your answers to two decimal places. z-score of Maria's age: z-score of Salma's age: (b) Relative to her population, who is the older faculty member?

An instructor claims that the average number of hours needed to study for a final exam in order to pass should be 5 hours. A student believes that the instructor is understating the number of hours needed to pass and surveys 36 students and finds the sample mean and standard deviation to be 5.7 and 1.5 hours respectively. Test the instructors claim at a .10 level.
The US mean height for adult men is = 68.5 inches, with a standard deviation of = 3 inches. The mean height for adult women is = 62.7 inches, with a standard deviation of = 2.7 inches. Who is taller relative to their gender, a man 75 inches tall, or a woman 68 inches tall?
A nutritionist wants to determine how much time nationally people spend eating and drinking. Suppose for a random sample of 901 people age 15 or older, the mean amount of time spent eating or drinking per day is 1.85 hours with a standard deviation of 0.57 hour. Complete C and D.
