    Standard Normal Curve   3.   In a recent year‚ about two-thirds of U.S. households purchased ground coffee.  Consider the annual ground coffee expenditures for households who purchase coffee‚ assuming that these expenditures are approximately normally distributed with a mean of $45.16 and a standard deviation of $10.00.       a.   Find the probability that a household spent less than $25.00.   Z=(25-45.16)/10= -2.016 =.4778=2.2%       b.   Find the probability that a household spent more than $50.00

    the following rules: i) Two out of three consecutive points fall beyond the 2σ limit on the same side of the centerline. ii) Four out of five consecutive points fall beyond the 1σ limit‚ on the same side of the centerline. iii) Eight consecutive points falling on one side of the centerline When the process is in statistical control‚ find the false alarm probability (Type-I error) for each case. The corresponding probability measures are obtained from the Normal table as P(3 " Z) = 0.00135

    Probability distribution Definition with example: The total set of all the probabilities of a random variable to attain all the possible values. Let me give an example. We toss a coin 3 times and try to find what the probability of obtaining head is? Here the event of getting head is known as the random variable. Now what are the possible values of the random variable‚ i.e. what is the possible number of times that head might occur? It is 0 (head never occurs)‚ 1 (head occurs once out of 2 tosses)
