Please provide me a explanation for the false statements. Thank you.

Answer each statement as true (T) or false (F). For all false statements an explanation should be given, i.e. an example, or theorem indicating that the statement is false. No explanation needed for true statements. - The value of the sinking fund should decrease over time. For payment made on a mortgage, the (nointerest) portion of the payment applied to the principal increases over time. When all subjects under study are used, the group is called a sample. Interviewing selected people at the local supermarket can be considered an example of random sampling. A measure obtained from a sample is called a parameter. Some permutations problems cab be solved by the basic counting rule. The number of combinations when 8 objects are selected from 8 different objects is 8. a device that is helpful in listing the outcomes of a sequence of events is a tree diagram. The transitive property is a valid method of proof. If the probability that an event will occur is 0.60, then the probability that will not occur is -0.60. -When two events are mutually exclusive, P(A or B) will equal P(A) + P(B). When two events cannot occur at the same time, they are said to be mutually exclusive. -When two events A and B are dependent, they much have the same probability of occurring. When two events A or B are dependent, P(A and B)=P(A). P(A|B). -An event and its complement can occur at the same time. When an event can't occur its probability is assumed to be -1. -If there are five contestants in a race, the number of ways the first- and second-place winners can be selected is 25. The range and midrange are both measures of variation. The standard deviation is the square root of the variance. The symbol for the population standard deviation is s. -If a person's score on an exam corresponds to 75th percentile, then that person obtained 75 correct answers out of 100 questions. When the mean of a data set is 18 and the standard deviation is 3, the z score for a value of 12 is -2. The total area under the normal curve is infinite. The mean of the standard normal deviation is equal to 0. The standard normal is a continuous distribution. The z value of a data value that is less than the mean of the data will always be negative. -P50, D5, Q2, and the median are the same for the values of a data set. -When the values in a data set are all different, there is not mode
