Consider the following sample observations on stabilized viscosity of asphalt specimens. 2,762 2,907 3,012 2,813 2,876 Suppose that for a particular application, it is required that true average viscosity be 3,000. Does this requirement appear to have been satisfied? State the appropriate hypotheses. (Use ? = 0.05.)

Next question A golf association requires that golf balls have a diameter that is 1.68 inches. To deter hform to the standard, a random sample of golf balls was selected. Their diameters are shown in the accompanying data table. Do the golf balls conform to the standards? Use the x = 0.01 level of significance. Click the icon to view the data table. First determine the appropriate hypotheses. Ho: H₁: (Type integers or decimals. Do not round.) Find the test statistic. (Round to two decimal places as needed.) Find the P-value. (Round to three decimal places as needed.) What can be concluded from the hypothesis test? O A. Reject Ho. There is sufficient evidence to conclude that the golf balls do not conform to the association's standards at the α = 0.01 level of significance. B. Do not reject Ho.

Vanadium has recently been recognized as an important trace element. An experiment was conducted to compare the concentrations of vanadium in different foods. The amount of vanadium, measured in nanograms per gram, was recorded for 8 samples of each of the following foods: green beans, tuna, and soy milk. The output from an ANOVA is shown below: State the null and alternative hypotheses to carry out ANOVA with these data. a) H0: Food products and level of vanadium are relatedHa: Food products and vanadium are not related b) H0: Food products and level of vanadium are not relatedHa: Food products and level of vanadium are related c) H0: There is a difference in the mean level of vanadium among the three food productsHa: There is no difference in the mean level of vanadium among the three food products d) H0: There is no difference in the mean level of vanadium among the three food productsHa: There is a difference in the mean level of vanadium among the three food…
