Have an exam tomorrow. Would like some help. These are the review questions that will be on my exam for Business Statistics. If you could just give me a summary on how to do these things on the ba ii plus calculator when needed.

Given a series of data. Calculate mean, median, mode, midrange, range, standard deviation, and 70th percentile.

Given independent variable x, and dependent variable y. Compute the regression equation y = a + bx (by BA II plus calculator), coefficient of correlation r, and predict the y value if x is given.

Given a value table. Compute the probabilities of A or B, A and B, and conditional probability.

Permutation, Combination.

Binomial distribution.

Given % of confidence, population standard deviation σ, and error E. Find the sample size n (how many ...?)

Given a small sample n, sample mean , sample standard deviation s, and % confident. Construct a confident interval.

Given a population mean μ, sample size n, sample mean , sample standard deviation s, and % significant level. Test the hypothesis (1 tail test or 2 tail test).
