An impоrtаnt quаlity chаracteristic used by the manufacturer оf Bоston and Vermont asphalt shingles is the amount of moisture the shingles contain when they are packaged. Customers may feel that they have purchased a product lacking in quality if they find moisture and wet shingles inside the packaging. In some cases, excessive moisture can cause the granules attached to the shingle for texture and coloring purposes to fall off the shingle, resulting in appearance problems. To monitor the amount of moisture present, the company conducts moisture tests. A shingle is weighed and then dried. The shingle is then reweighed, and, based on the amount of moisture taken out of the product, the pounds of moisture per 100 square feet are calculated. The company would like to show that the mean moisture content is less than 0.35 pound per 100 square feet. The manufacturer knows that the populations standard deviation is 0.1275 pounds per 100 square feet. The file here includes 36 measurements (in pounds per 100 square feet) for Boston shingles and 31 for Vermont shingles. For the Vermont shingles, you want to test if there is evidence at the 0.05 level of significance that the population mean moisture content is less than 0.35 pound per 100 square feet. What are the values of the sample size: [n] test statistic: [t] sample statistic: [s] lower critical value: [lc] (enter NA for not applicable) upper critical value: [uc] (enter NA for not applicable) p-value: [p] Hint: Use PHStat/Excel to answer the question.

One оf the issues fаcing оrgаnizаtiоns is increasing diversity throughout the organization. One of the ways to evaluate an organization’s success at increasing diversity is to compare the percentage of employees in the organization in a particular position with a specific background to the percentage in a particular position with that specific background in the general workforce. Recently, a large academic medical center determined that 9 of 17 employees in a particular position were female, whereas 55% of the employees for this position in the general workforce were female. At the 0.05 level of significance, is there evidence that the proportion of females in this position at this medical center is less than what would be expected in the general workforce? What are the values of the sample size: [n] test statistic: [t] sample statistic: [s] lower critical value: [lc] (enter NA for not applicable) upper critical value: [uc] (enter NA for not applicable) p-value: [p] Hint: Use PHStat/Excel to answer the question.
