A population of values has a normal distribution with u = 69.4 and o = 18.9. You intend to draw a random sample of size n = 185. Please show your answers as numbers accurate to 4 decimal places.
Find the probability that a single randomly selected value is between 65.9 and 68.8.
P(65.9 < X < 68.8) =
Find the probability that a sample of size n = 185 is randomly selected with a mean between 65.9 and 68.8.
P(65.9 < < 68.8) =

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
