To determine The description of an exponential scale. Also, to explain when an exponential scale is useful. Explanation Given: What is an exponential scale? When is an exponential scale useful? Exponential Scale: A scale is a leveled range of values (or) numbers from lowest to highest that measures something at regular intervals. A great example is the classic number line that has numbers lined up at consistent intervals along a line. A Linear scale is much like the classic number line. A change between two values is considered on the basis of the difference between the values. Thus, for example, a change from 1 t o 2 would be considered as the same amount of increase as from 5 t o 6 on a linear scale. The definition of a Logarithmic Scale is one in which the units on the axis are powers, or logarithms, of a base number, and it is typically used when the increase or decrease in value on that axis is exponential. Most often, the base used is 10 . If only one axis uses a logarithmic scale, then it is defined as a semi-log chart. It both axes use a logarithmic scale, then it is defined as a log-log chart. A logarithmically scaled axis can never represent zero or a negative number, because there is no power to which we can raise a base number to get numbers less than or equal to zero. A change between two values is considered on the basis of the ratio of the two values on a logarithmic scale...

Continuous Probability Distributions

Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could co…

(b) An otherwise fair six-sided die has been tampered with in an attempt to cheat at a dice game. The effect is that the 1 and 6 faces have a different probability of occurring than the 2, 3, 4 and 5 faces. Let θ be the probability of obtaining a 1 on this biased die. Then the outcomes of rolling the biased die have the following probability mass function. Table 1 The p.m.f. of outcomes of rolls of a biased die Outcome 1 2 3 4 5 6 Probability θ 1 4 (1 − 2θ) 1 4 (1 − 2θ) 1 4 (1 − 2θ) 1 4 (1 − 2θ) θ (i) By consideration of the p.m.f. in Table 1, explain why it is necessary for θ to be such that 0 < θ < 1/2. [2] (ii) The value of θ is unknown. Data from which to estimate the value of θ were obtained by rolling the biased die 1000 times. The result of this experiment is shown in Table 2.
