A sample of size n taken from a population with mean = µ and standard deviation = σ has sample mean = µ and sample s.d. = σ/√n.
If the final exam scores are normally distributed, and X is a random variable for the mean of a sample, then
Pr[X < 70] = Pr[(X - 73) / (7.8/√24) < (70 - 73) / (7.8/√24)]
… ≈ Pr[Z < -1.8842]
… ≈ 0.0298
(where Z is normally distributed with µ = 0 and σ = 1).
Thus, the required equation is given by Y = 5/2X.
Given data can tabulate is
Days overdue(x) = 0 2 4 6 8 10
Amount of fine(y) = 0 5 10 15 20 25
<h3>What is equation?</h3>
equation is the relationship between variable and represented as is example of polynomial equation.
Since, the as for every value of x, y grows linerely.
Equation can be given as for every 2 step of x, y increase 5 steps
therefore, y = 5/2x
Thus, The required equation is given by y = 5/2x
