A: As per our guidelines, we are supposed to answer the only questions. If A and B are independent events, with P(A) = 0.50 and P(B) = 0.70, then the probability that A occurs or B occurs or both occur is: The collection of all possible outcomes of an experiment is called: Two events A and B are said to mutually exclusive if: If A and B are mutually exclusive events with P(A) = 0.80, then P(B): A useful graphical method of constructing the sample space for an experiment is: The expected number of heads in 90 tosses of an unbiased coin is: The expected value, E(X), of a binomial probability distribution is: Given that X is a binomial random variable, the binomial probability P(X x) is approximated by the area under a normal curve to the right of: The standard deviation of a binomial distribution for which n = 100 and p = .35 is: Which of the following best describes a discrete random variable? Multiple Choice O Histograms are used to display discrete numerical data. Concepts and reason 71 Which of the following is true about a stem-and-leaf display?

Group 2 Which of the following are TRUE statements? III. what it means is the numbers that are between and are 30 and 59. Each bar typically covers a range of numeric values called a bin or class; a bar's height indicates the frequency of data points with a value within the corresponding bin. The statements that must be true about the data sets A and B displayed in the histogram are; The mean of dataset A is equal to the mean of dataset B, The median of data set A is equal to the median value of dataset B, The range of dataset A is equal to the range. Kwame Lucas delivers bread for City Bakery Company. a- A histogram is a summary of interval data. shows shape of distribution shows location of center shows the spread of data classes. The heights of the bars represent class frequencies. The classes in a histogram cover the complete range of observations. 11 Class The median values for dataset A and dataset B are both in the median range of 30 and 40, therefore; Another obvious information that can be seen and which must be true is the range; The range is the difference between the largest number and the smallest number; The range of the histogram of data set A = 60 - 10 = 50, The range of the histogram of data set B = 60 - 10 = 50, This site is using cookies under cookie policy .
