QUESTION 3Four different insulator products made of different rubber mixtures are being tested. One of thetested features of the products is their tensile strength. Therefore, a random sample of insulatorproducts drawn from each mixture is used to determine whether there is variability in the meantensile strength data. Table 2 shows the measured data on tensile strength in grams per squarecentimetre.A16.821.420.121.519.218.5Rubber MixtureBс16.919.516.4 18.917.118.620.9 20.515.818.1D14.620.316.417.5Table 2Design your analysis at the 0.025 and 0.25 significance levels from tabulated data.

Research was conducted on the amount of oxygen runners could utilize during training, known as their VO2 max, and their finishing times for a 5K race to see if there was a significant relationship between these variables. The results for 8 runners were compiled and placed in the following table.

Researchers believe that students who study from a screen (e.g., phone, computer) have different grades than students who study from physical pages (e.g., notes). To test this hypothesis, one professor identifies a sample of n = 16 students who study from a screen. They had an average score of M = 72.5 on the final exam. The average for the population of students for the final exam is Mu = 77, σ = 8 and forms a normal distribution. Based on this sample, does the professor have enough evidence to support the researcher’s belief at an α = .05 level? The researcher will use a one-sample z-test. All assumptions have been met.

However, the current mach tion of 0.15 ounces and the new machine had a standard deviatic es.Carry out the appropriate hypothesis test at the a = 0.05 lev ..

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.20 ml/kg for the distribution of blood plasma.

Trace metals in drinking water affect the flavor and an unusually high concentration can pose a health hazard. Ten pairs of data were taken measuring zinc concentration in bottom water and surface water. The raw data provided in table below.

I have asked this question twice and both times it has been wrong. Answer given F=.82 and .77 both these are incorrect. A bakery is considering buying one of two gas ovens. The bakery requires that the temperature remain constant during a baking operation. A study was conducted to measure the variance in temperature of the ovens during the baking process. The variance in temperature before the thermostat restarted the flame for the Monarch oven was 3.3 for 22 measurements. The variance for the Kraft oven was 4 for 25 measurements. Does this information provide sufficient reason to conclude that there is a difference in the variances for the two ovens? Assume measurements are normally distributed and use a 0.02 level of significance.
