the R-squared (coefficient of determination) in regression output. Fourth‚ the regression model should be evaluated for serial correlation. The Durbin-Watson statistic is used in this regard. The problem of serial correlation is common to time-series data and leads to the problem of spurious regression‚ i.e.‚ misleading regression statistics. 2.

TUTORIAL 4 – DISCRETE DISTRIBUTIONS Question 1 An experiment consists of picking a card at random from a standard deck of cards and replacing it. If this experiment is performed 12 times‚ what is the probability that you get: (a) exactly 2 aces; (b) exactly 3 hearts; (c) more than 1 heart. Solution Let n = 12‚ the no of experiments. (a) Let p = probability of obtaining an ace in an experiment of picking a card at random from a standard deck of cards; and = 4/52 = 1/13

Exercise 36 Answers 1. Since the F value is significant‚ based on the p-value of 0.005 which is less than 0.05 which is sufficient to reject the null hypothesis. This suggests that there is a difference in the control and treatment groups. 2. Since the p- value is less than 0.05 and therefor the null hypothesis can be rejected. This presents that the mean‚ difficulty and mobility scores‚ must be different 3. The result was statistically significant with a probability score of p < 0.001. 4. Yes

PROBABILITY DISTRIBUTION In the world of statistics‚ we are introduced to the concept of probability. On page 146 of our text‚ it defines probability as "a value between zero and one‚ inclusive‚ describing the relative possibility (chance or likelihood) an event will occur" (Lind‚ 2012). When we think about how much this concept pops up within our daily lives‚ we might be shocked to find the results. Oftentimes‚ we do not think in these terms‚ but imagine what the probability of us getting behind
