An experiment was carried out to compare flow rates for four different types of nozzle. Samplesizes were 5, 6, 7, and 6, respectively, and calculations gave f= 3.68. The relevant hypothesisusing alpha = 0.01 are:O a. Ho: mu1 = mu2 = mu3 = mu4 = musHa: At least two of the mui'S are differentO b.

A sociologist is investigating the relationship between job satisfaction and work-life balance. For a sample of 18 individuals, the following data is obtained: Job Satisfaction: M = 4.0 SS = 16.0 Work-Life Balance: M = 6.0 SS = 134.0 SP = 32.0 r= .69 d. Conduct a hypothesis test using an alpha level of α = .01 to determine if the correlation is significant. Include all steps.
3.81Four different printing processes are being compared to study the density that can be reproduced. Density readings are taken at different dot percentages. As the dot percentage is a source of variability, a completely randomized block design has been used and the data obtained are given in Table 3.28. Analyse the data and draw the conclusions.

What does the statistical significance of the results above imply? OA. A difference in conclusions between two hypothesis tests does not necessarily mean that the test with the result that is deemed "statistically significant" is actually much more significant than the test with the result that is deemed "not statistically…

In an experiment to compare the tensile strengths of I = 6 different types of copper wire, J = 5 samples of each type were used. The between-samples and within-samples estimates of o? were computed as MSTr = 2654.3 and MSE = 1154.2, respectively. Use the F test at level 0.05 to test Ho: 4, = µ, = ... = lg versus H: at least two u's are unequal. You can use the Distribution Calculators page in SALT to find critical values and/or p-values to answer parts of this question. Calculate the test statistic. (Round your answer to two decimal places.) f = What can be said about the P-value for the test?

An experiment to compare the tension bond strength of polymer latex modified mortar (Portland cement mortar to which polymer latex emulsions have been added during mixing) to that of unmodified mortar resulted in x = 18.19 kgf/cm? for the modified mortar (m = 42) and y = 16.85 kgf/cm? for the unmodified mortar (n = 30). Let u, and u, be the true average tension bond strengths for the modified and unmodified mortars, respectively. Assume that the bond strength distributions are both normal. Assuming that o, = 1.6 and o, = 1.3, test Hn: 4, - H, = 0 versus H: u, - u, > 0 at level 0.01. Calculate the test statistic and determine the P-value.

The average age for licensed drivers in a county is µ = 41.6, σ = 12, and the distribution is approximately normal. A county police officer was interested in whether the average age of drivers receiving speeding tickets differed from the average age of the driving population. She obtained a sample of N = 16 drivers with speeding tickets. The average age for this sample was M = 34.4 and alpha = 0.05. calculate statistical power for this study.
