The management of White Industries is considering a new method of assembling its golf cart. The present method requires 42.3 minutes, on the average, to assemble a cart. The mean assembly time for a random sample of 24 carts, using the new method, was 40.6 minutes, and the standard deviation of the sample was 2.7 minutes. Using the .10 level of significance, can we conclude that the assembly time using the new method is faster?
The dimension is supposed to be 224 mm and the variability of the manufacturing process is unknown. Is there evidence that the mean dimension is not 224 mm?
Build a scatter plot, Find the value of the linear correlation coefficient r, and find the critical value of r using α=0.05. Determine whether there is sufficient evidence to support a claim of a linear correlation between the two variables.
Determine the test value? Use α = 0.05. (Use the variances unequal formula).
