Active management of labor (AML) is a group of interventions designed to help reduce the length of labor and the rate of cesarean deliveries. Physicians from the Department of Obstetrics and Gynecology at the University of New Mexico Health Sciences Center were interested in determining whether AML would also translate into reduced cost of delivery. According to their study, 500 AML deliveries had a sample mean cost of $2,480 dollars with a sample standard deviation of $766. The average cost of all AML deliveries is to be estimated with 90% confidence interval. a. The t − or z −value that should be used to construct this interval is b. The margin of error is equal to c. The confidence interval is

Nutrition Iron-deficiency anemia is an important nutritional health problem in the United States. A dietary assessment was performed on 56 boys 9 to 11 years of age whose families were below the poverty level. The mean daily iron intake among these boys was found to be 12.40 mg with standard deviation 4.71 mg. Suppose the mean daily iron intake among a large population of 9- to 11-year-old boys from all income strata is 14.41 mg. We want to test whether the mean iron intake among the low-income group is different from that of the general population. You can use the Inferential Statistics page and the Distribution Calculators page in SALT to answer parts of this question. (a) State the hypotheses (in mg) that we can use to consider this question.

Yellowstone Park Medical Services (YPMS) provides emergency health care for park visitors. Such health care includes treatment for everything from indigestion and sunburn to more serious injuries. A recent issue of Yellowstone Today (National Park Service Publication) indicated that the average number of visitors treated each day by YPMS was 21.7. The estimated standard deviation was 4.2 (summer data). The distribution of numbers treated is approximately mound-shaped and symmetric. (a) For a 10-day summer period, the following data show the number of visitors treated each day by YPMS. Day 1 2 3 4 5 6 7 8 9 10 Number treated 25 19 17 15 20 24 30 19 16 23 Make a control chart for the daily number of visitors treated by YPMS, and plot the data on the control chart. (Be sure to include the horizontal lines on the control chart. Recall that the mean line is solid and the control limit lines are dashed.) For another 10-day summer period, the following data were obtained. Day…

Bone mineral density (BMD) is a measure of bone strength. Studies show that BMD declines after age 45. The impact of exercise may increase BMD. A random sample of 59 women between the ages of 41 and 45 with no major health problems were studied. The women were classified into one of two groups based upon their level of exercise activity: walking women and sedentary women. The 39 women who walked regularly had a mean BMD of 5.96 with a standard deviation of 1.22. The 20 women who are sedentary had a mean BMD of 4.41 with a standard deviation of 1.02. Which of the following inference procedures could be used to estimate the difference in the mean BMD for these two types of women
Sigmund Schwinn owns a popular bike shop called Cycle Analysts located in Ventura. Sigmund is participating in a bike show in San Francisco next month. At the show, he will have a special promotion on the Ninja Trail Master bike for $2,000 each. Estimated demand for this bike at the show is a normal distribution with a mean of 600 and a standard deviation of 20. Sigmund's cost is $1,000 per bike. Sigmund has already rented a large, one- way U-Haul truck to take the bikes to San Francisco. Each bike not sold at the show will be sold to a local bike vendor at a new loss of $200 to Sigmund. If Sigmund does not bring enough bikes to show, he will have to reduce the price to the customer by $200 and pay an additional $100 shipping to deliver the bike to the customer's residence using UPS next day delivery from Ventura. a. What is the probability that demand will be between 580 and 620 bikes? b. What is the probability that demand will be between 570 and 610? C. What is the unit cost of…
Low‑density lipoprotein, or LDL, is the main source of cholesterol buildup and blockage in the arteries. This is why LDL is known as "bad cholesterol." LDL is measured in milligrams per deciliter of blood, or mg/dL. In a population of adults at risk for cardiovascular problems, the distribution of LDL levels is normal, with a mean of 123123 mg/dL and a standard deviation of 4141 mg/dL. If an individual's LDL is at least 11 standard deviation or more above the mean, he or she will be monitored carefully by a doctor. What percentage of individuals from this population will have LDL levels 11 or more standard deviations above the mean? Use the 6868–9595–99.799.7 rule. (Enter your exact answer as a whole number.)
