Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

275 295 300 285 290 300 250 260
The population mean content is 275 ml. Assume that the distribution
of the soft drinks contents be normal. Is there a significant difference
between the sample and the population mean contents of the soft
drinks? Use a 90% confidence level?

10. An engineering study was undertaken to determine the optimum thickness of aluminum to be used to construct cans to be used for cat food. Cans made of aluminum of thickness 2.10 mm and 1.90 mm were tested to determine the maximum load each would sustain before collapsing. The sample data is summarized below. Use a = 0.05 to test the claim that the thicker cans are stronger (will withstand a higher load). 2.10 mm thick 1.90 mm thick sample size 175 170 mean maximum load (kg) 28.18 26.71 standard deviation of maximum load (kg) | 2.78 2.21
A researcher wonders whether younger mothers have babies that are significantly heavier or lighter than the population average of μ 7.25 pounds. The researcher collects data from N = 35 babies who were born to mothers between the ages of 16 and 18. The average weight for these babies was M = 7.15 pounds (SD = .6 pounds).

2.5. A sample of 15 g carbonated salt with density of 2650 kg/m3 is poured into a liter of water to form a suspension. The prepared suspensionwas used to fill up an Andreasen Pipette vessel to the 20 cm mark. Suspension samplesweretaken at:2,8, 16,32, 60,120, 180, 240, 360, 480, 600, and 1440 min. The weight concentrations on10 mL of the every extracted samplewere:0.1465,0.0967,0.0883, 0.0632, 0.0386,0.0294, 0.0178,0.0104, 0.0073,0.0051,0.0030, and 0.0008 g. If every extracted sample drops the height level inthe vessel 0.5 cm, evaluate the median size of the carbonated salt particles.

How heavy a load (pounds) is needed to pull apart pieces of Douglas fir 4 inches long and 1.5 inches square? Students doing a laboratory exercise sample 20 pieces of wood and find an average load capacity of 30,841 pounds. We are willing to regard the wood pieces prepared for the lab session as an SRS of all similar pieces of Douglas fir. Engineers also commonly assume the characteristics of materials vary normally. Suppose that the strength of pieces of wood like these follow a normal distribution with a population standard deviation of 3,000 pounds (As you can see all three necessary assumptions are met). a. Assuming that all evergreen wood has a known "load" capacity average of 30,000 pounds. Make a two-sided hypothesis (null and alternative statement) about Douglas Fir "load" capacity compared to the overall average. b.
