At a specific service station, 35% of the clients utilize normal gas, 35% use in addition to

gas, and 30% utilize premium. Of those clients utilizing ordinary gas, just 30%

fill their tanks. Of those clients utilizing also, 40% fill their tanks, though of

those utilizing top notch, 35% fill their tanks.

a. What is the likelihood that the following client will demand in addition to gas and not

fill the tank?

b. What is the likelihood that the following client fills the tank?

c. In the event that the following client doesn't fill the tank, what is the likelihood that ordinary

gas is mentioned? In addition? Premium?

A hypothesis test is to be performed for the mean of the population from which the data were obtained. Use the graphs to determine whether a z-test, a t-test, a Wilcoxon signed-rank test, or none of these is appropriate.

The varieties are known to have varying levels of susceptibility to iron deficiency. The data are average chlorosis scores based on a scale of 1 to 9, with 1 being the best plant condition and 9 the worst. Use F test for randomized complete block design for differences among the varieties. Blocks Variety 2 3 4 Means Susceptible 4.5 6.3 5.7 5.3 Moderately 3.5 4.3 3.3 5.0 resistant Resistant 1.0 1.3 1.0 1.7 MeansConsider the following incomplete ANOVA table: SS DF MS F 50 1 50 ? 80 2 40 ? 30 2 15 ? ? 12 '? 172 17 In addition to the ANOVA table, you know that the experiment has been replicated three times, and that the totals of the three replicates are 10, 12, and 14, respectively. The original experiment was run as a completely randomized design. Answer the following questions: (a) Estimate the standard deviation of the sample observations, and complete the ANOVA table. (b) Suppose that the experiment has been run in blocks, with each replicate a block, so that it is a randomized complete block design. What is the number of degrees of freedom for blocks? Compute the block sum of squares. (c) Reconstruct the ANOVA table for the randomized complete block design
