Use the following listed chest deceleration measurements (in g, where g is the force of gravity) fromsamples of small, midsize and large cars. Assume that we plan to use a 0.05 significance level to test theclaim that the different size categories have the same mean chest deceleration in the standard crash test.SmallMidsizeLargeESCOLARUNIVERSITY4436323953451907374341544238395237444942 Answer this question using the One-Way ANOVA with Equal Sample Sizes:Weights (kg) of poplar trees were obtained from trees planted in a sandy and dry region. The trees weregiven different treatments identified in the table below. Use a 0.05 significance level to test the claim thatthe four treatment categories yield poplar trees with the same mean weight. Is there a treatment thatappears to be most effective in the sandy and dry region?UNIVERSITYFertilizer andNo TreatmentFertilizerIrrigationIrrigation19070.601.160.650.221.110.930.082.130.070.300.622.330.070.590.011.740.440.170.030.12

Read the problem below and answer the following questions. 1) What statistical test should be used to solve this problem? 2) State the null and alternative hypotheses for the test. Bicep strength (kg/cm2) was measured in 2 groups of 12 males each (age=18-25). One group received a hormone injection (H) and the other did not (NH). Is mean bicep strength greater in the group receiving the hormone injection? For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac). BIUS Paragraph Arial 14px A V ...

Values of modulus of elasticity (MOE, the ratio of stress, i.e., force per unit area, to strain, i.e., deformation per unit length, in GPa) and flexural strength (a measure of the ability to resist failure in bending, in MPa) were determined for a sample of concrete beams of a certain type, resulting in the following data: MOE 29.7 33.1 33.6 35.2 35.4 36.2 36.2 36.3 37.4 37.8 Strength 5.8 7.1 7.2 6.2 8.0 6.9 7.1 7.7 6.7 6.4 МОЕ 38.6 38.7 39.7 40.9 42.7 42.7 43.6 45.7 45.9 46.8 Strength 7.1 6.4 8.0 8.9 8.3 8.8 7.9 9.6 7.3 7.6 МОЕ 47.9 49.2 51.6 62.7 69.7 79.6 80.1 Strength 9.8 7.7 7.8 11.5 11.4 11.9 10.6 Fitting the simple linear regression model to the n = 27 observations on x = modulus of elasticity and y = flexural strength given in the data above resulted in ý = 7.589, s, = 0.180 when x = 40 and ý = 9.749, s, = 0.255 for x = 60.
