- Compute for the most appropriate measure of central tendency.The absolute viscosity for sunflower oil is supposed to average 0.0311 Pa⋅s at 38 ∘C. Suppose a food scientist collects a random sample of 4 quantities of sunflower oil and computes the mean viscosity for his sample to be x¯=0.0318 Pa⋅s at 38 ∘C. Assume that measurement errors are normally distributed and that the population standard deviation of sunflower oil viscosity is known to be σ=0.0009 Pa⋅s. The scientist will use a one‑sample z‑test for a mean, at a significance level of α=0.01, to evaluate the null hypothesis, H0:μ=0.0311 Pa⋅s against the alternative hypothesis, H1:μ≠0.0311 Pa⋅s. Complete the scientist's analysis by calculating the value of the one-sample z‑statistic, the p‑value, and then deciding whether to reject the null hypothesis. First, compute the z‑statistic, z. Provide your answer precise to two decimal places. Avoid rounding within calculations. z= Determine the P-value of the test using either a table of standard normal critical values or…Assume that the helium porosity ( in percentage) of sample taken from any particular seam is normally distributed with true standard deviation of 0.75
- how to find that which type of kurtosis is represent by the curve in sample distribution.A park ranger is searching for bears in a region of the park where on average there are 5 bears per square mile. The bears are solitary independent creatures, so it is reasonable to assume that the numbers of bears in disjoint regions are independent unknowns and that the number expected in any region is proportional to the area of the region. The ranger can also assume that in a very tiny region, say a square inch, it is impossible to find more than one bear. What is the standard deviation in area (in square miles) he has to search in order to find 16 bears?A study was conducted by a group of neurosurgeons. They compared a dynamic system (Z-plate) and a static system (ALPS plate) in terms of the number of acute postoperative days in the hospital spent by the patients. The descriptive statistics for these data are as follows: for 14 patients with dynamic system, the sample mean number of acute postoperative days was 7.36 with standard deviation of 1.22; for 6 patients with static system the sample mean number of acute postoperative days was 10.5 with sample standard deviation of 4.59. Assume that the numbers of acute postoperative days in both populations are normally distributed. We wish to estimate µ1 − µ2 with a 99 percent confidence interval. Can you assume unknown population variance are equal. a. Degrees of freedom and t-value are b. Margin of error and confidence interval are c. Based on your interval in part (b), we can state with 99 percent confidence that the average numbers of acute postoperative days in two populations i.…

(b) How large a sample size is necessary if the width of the 95% two-sided CI is to be 0.5? (c) Compute a 98% upper one-sided CI for true average porosity of another seam based on 16 specimens with a sample average porosity of 4.56.show major intermediate steps.If there is a linear relationship between the response y (characteristic under study) and an auxiliary variable x such that when x=0 (assuming total population x is known) the value of y does not equal to zero, then name the best possible method of estimation to estimate population total.Stating the assumptions made, obtain bias and variance of the estimate.Poly(3-hydroxybutyrate) (PHB), a semicrystalline polymer that is fully biodegradable and biocompatible, is obtained from renewable resources. From a sustainability perspective, PHB offers many attractive properties though it is more expensive to produce than standard plastics. The accompanying data on melting point (°C) for each of 12 specimens of the polymer using a differential scanning calorimeter appeared in an article.

- According to the records of the last 15 years, the average rainfall in the Marmara region in March is 13 cm and the standard deviation is 4 cm. In the Aegean region, according to the records of the last 10 years, the average precipitation for the same month is 19 cm and the standard deviation is 2 cm. Assuming that the observations were taken from normally distributed masses with different variances, test the hypothesis that the mean precipitation in March is equal with an error of 0.05.Suppose that the blood pressure of the human inhabitants of a certain Pacific island is distributed with mean, μ = 90 mmHg and standard deviation , σ = 8 mmHg. According to Chebyshev's Theorem, at least what percentage of the islander's have blood pressure in the range from 74 mmHg to 106 mmHg ?1. Microprocessor chips coming off of a Fab line are tested to divide them into 3 speed categories: 2GHz, 3GHz, and 6GHz. 900 chips are tested with 200 being placed in the 2GHz category, 400 being placed in the 3GHz category, and 300 being placed in the 6GHz category. a) What is the average speed of this batch of chips?
