Consider the following questions:How much does milk cost on the East Coast of the United States? How many minutes does it take to drive 30 miles at an average speed of 55 miles per hour?What is the age difference between you and your siblings?How many hours of sleep do teenagers get during the school year compared to summer vacation?Define each question as being or not being a statistical question and explain why. (75–150 words, or 1–2 paragraphs)Joan Horton is a building contractor whose company builds many homes every year. In planning for each job, Joan needs some idea about the direct labor hours per square foot required to build a home. She has collected sample information on the labor hours for 10 jobs during the past year.

If Joan had to select the mean or the median as the estimate of direct labor hours, what factors about each statistic should she consider before making the decision?Calculate the sample variance and standard deviation. How can Joan use these values in planning future jobs?One of Joan’s competitors, J.M. Sawyer, has numbers claiming that his crews average 350 hours per square foot, with a standard deviation of 50. Sawyer further claims that his company is more consistent in direct labor hours applied to houses than Horton’s company. Who is right, and why?The weekly total of hours for the servers and the cooks for a small restaurant are listed below. Find the range, variance, and standard deviation for each set. Which set of data is more variable?

Discuss why this is important in your practice and with patient interactions.2.Evaluate and provide examples of how hypothesis testing and confidence intervals are used together in health care research. Provide a workplace example that illustrates your ideas.

Find a study where the distribution follows a normal or bell-shaped curve. An example of a normal distribution or bell-shaped curve, called “Heights of Red Pine Seedlings”, is located in the beginning of Chapter 6 in the book. Cite the source of the study you’ve selected, and explain why you think the distribution is bell shaped. For instance, if the study is about income, then the income may be low for a child and peak at age forty-five and then gradually drop.
