(A) Construct a 90% confidence interval for the difference between the proportions of unacceptable assemblies generated by the two teams.

(B) Based on the confidence interval constructed in (A), is there sufficient evidence to conclude, at the 10% significance level, that the two teams differ with respect to their proportions of unacceptable assemblies?

(C) Is there sufficient evidence to conclude, at the 10% significance level, that the two teams differ with respect to their proportions of unacceptable assemblies? Conduct the appropriate hypothesis test.

(D) Calculate the p-value and explain how to use it for testing the null hypothesis of equal proportion.
