- Shear strength measurements derived from unconfined compression tests for two types of sols gave the results shown in the following table (measurements in tons per square foot). Do the soils appear to differ with respect to the variation of the shear strength, at the 10% significance level? Soil Soil Type Турe l II sample size 10 sample 1.57 1.92 mean sample std dev 0.17 0.22 Let the strength measurement of soil type I be the first population and the strength measurement of soil type II be the second. a. Choose the answer : 1) Alternative Hypothesis: The population variation of the shear strength for soil type l is > that of soil type I. 2) Alternative Hypothesis: The population variation of the shear strength for soil type I is < that of soil type II. 3) Alternative Hypothesis: The sample variation of the shear strength for soil type l is not equal to that of soil type II. 4) Alternative Hypothesis: The population variation of the shear strength for soil type l is not equal to that of…The table below shows the results from the specific gravity (S.G.) test performed in a soil laboratory including twenty samples of sand.

- Please show me your solutions and interpretations. Show the completehypothesis-testing procedure.A manufacturing company produces bearings. One line of bearings is specified to be 1.64 centimeters (cm) in diameter. A major customer requires that the variance of the bearings be no more than 0.001 cm2. The producer is required to test the bearings before they are shipped, and so the diameters of 16 bearings are measured with a precise instrument, resulting in the following values:1.69 1.62 1.63 1.70 1.66 1.63 1.65 1.71 1.64 1.69 1.57 1.64 1.59 1.66 1.63 1.65Assume bearing diameters are normally distributed. Use the data and α = 0.025 to test the data to determine whether the population of these bearings is to be rejected because of too high variance.use the previous data its the contueniousationThe following scatterplot shows the mean annual carbon dioxide (CO,) in parts (CO2) per million (ppm) measured at the top of a mountain and the mean annual air temperature over both land and sea across the globe, in degrees Celsius (C).
