Explanation Given: The table gives proportions of people over age 15 in the U.S. population and proportions of people who live alone in a recent year. Age Proportion of population age 15 or higher Proportion of people living alone 15 − 24 .173 .034 25 − 34 .170 .100 35 − 44 .163 .089 45 − 64 .332 .152 65 and higher .161 .289 Formula Used: P ( B | A ) = P ( B ) ⋅ P ( A | B ) P ( B ) ⋅ P ( A | B ) + P ( B ′ ) ⋅ P ( A | B ′ ) It is known as Bayes Formula. Calculation: Let P 1 be the event where person age is 15 − 24 , similarly for other age group event be P 2 , P 3 , P 4 , and P 5 . And let A be the event that person lives alone then, P ( A | P 1 ) = 0.034 P ( A | P 2 ) = 0.100 P ( A | P 3 ) = 0.089 The probability of randomly selected people whose age is between 45 and 64 given that person lives alone will be P ( P 4 | A )

Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of tw…

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow compar…

7. Show that for R sufficiently large, the polynomial P(z) in Example 3, Sec. 5, satisfies the inequality |P(z)| R. Suggestion: Observe that there is a positive number R such that the modulus of each quotient in inequality (9), Sec. 5, is less than |an|/n when |z| > R.

9. Establish the identity 1- 1+z+z² + 2n+1 ... +z" = 1- z (z1) and then use it to derive Lagrange's trigonometric identity: 1 1+ cos cos 20 +... + cos no = + 2 sin[(2n+1)0/2] 2 sin(0/2) (0 < 0 < 2л). Suggestion: As for the first identity, write S = 1+z+z² +...+z" and consider the difference S - zS. To derive the second identity, write z = eie in the first one.

8. Prove that two nonzero complex numbers z₁ and Z2 have the same moduli if and only if there are complex numbers c₁ and c₂ such that Z₁ = c₁C2 and Z2 = c1c2. Suggestion: Note that (i≤ exp (101+0) exp (01-02) and [see Exercise 2(b)] 2 02 Ꮎ - = = exp(i01) exp(101+0) exp (i 01 - 02 ) = exp(102). i 2 2
