Chapter 1: Q2E (page 12)

For each of the following hypothetical populations, give

a plausible sample of size 4:

a. All distances that might result when you throw a football

b. Page lengths of books published 5 years from now

c. All possible earthquake-strength measurements (Richter scale) that might be recorded in California during the next year

d. All possible yields (in grams) from a certain chemical reaction carried out in a laboratory.

Short Answer

Expert verified

a.\(\left\{ {50,45,40,35} \right\}\)

b.\(\left\{ {700,490,800,500} \right\}\)

c.\(\left\{ {5.2,{\rm{ }}6.5,{\rm{ }}5,{\rm{ }}7} \right\}\)

Step by step solution

01

Given information

Four populations are provided

02

Provide one possible sample of size 4.

a.

The possible sample of size 4 for all distances that might result when a football is thrown is given as,

\(\left\{ {50,45,40,35} \right\}\)

b.

The possible sample of size 4 for page lengths of books published 5 years from now is given as,

\(\left\{ {700,490,800,500} \right\}\)

03

Provide one possible sample of size 4.

c.

The possible sample of size 4 forall possible earthquake-strength measurements (Richter scale) that might be recorded in California during the next yearis given as,

\(\left\{ {5.2,{\rm{ }}6.5,{\rm{ }}5,{\rm{ }}7} \right\}\)

d.

The possible sample of size 4 forall possible yields (in grams) from a certain chemical reaction carried out in a laboratoryis given as,

\(\left\{ {60{\rm{gm}},{\rm{ }}57{\rm{gm}},{\rm{ }}40{\rm{gm}},{\rm{ }}80{\rm{gm}}} \right\}\)

Let \({\rm{X}}\) denote the amount of space occupied by an article placed in a \({\rm{1 - f}}{{\rm{t}}^{\rm{3}}}\) packing container. The pdf of \({\rm{X}}\) is

\({\rm{f(x) = }}\left\{ {\begin{array}{*{20}{c}}{{\rm{90}}{{\rm{x}}^{\rm{8}}}{\rm{(1 - x)}}}&{{\rm{0 < x < 1}}}\\{\rm{0}}&{{\rm{ otherwise }}}\end{array}} \right.\)

a. Graph the pdf. Then obtain the cdf of \({\rm{X}}\) and graph it. b. What is \({\rm{P(X}} \le {\rm{.5)}}\) (i.e., \({\rm{F(}}{\rm{.5)}}\))? c. Using the cdf from (a), what is \({\rm{P(}}{\rm{.25 < X}} \le {\rm{.5)}}\)? What is \({\rm{P(}}{\rm{.25}} \le {\rm{X}} \le {\rm{.5)}}\)? d. What is the \({\rm{75th}}\) percentile of the distribution? e. Compute \({\rm{E(X)}}\) and \({{\rm{\sigma }}_{\rm{X}}}\). f. What is the probability that \({\rm{X}}\) is more than \({\rm{1}}\) standard deviation from its mean value?

Suppose your waiting time for a bus in the morning is uniformly distributed on\((0,8)\), whereas waiting time in the evening is uniformly distributed on\((0,10)\)independent of the morning waiting time.

a. If you take the bus each morning and evening for a week, what is your total expected waiting time?

b. What is the variance of your total waiting time?

c. What are the expected value and variance of the difference between morning and evening waiting times on a given day?

d. What are the expected value and variance of the difference between total morning waiting time and total evening waiting time for a particular week?

The actual tracking weight of a stereo cartridge that is set to track at \({\rm{3 g}}\) on a particular changer can be regarded as a continuous rv \({\rm{X}}\) with pdf

\({\rm{f(x) = \{ }}\begin{array}{*{20}{c}}{{\rm{k(1 - (x - 3}}{{\rm{)}}^2})}&{{\rm{2}} \le {\rm{x}} \le {\rm{4}}}\\{\rm{0}}&{{\rm{otherwise}}}\end{array}\)

a. Sketch the graph of \({\rm{f(x)}}\).

b. Find the value of \({\rm{k}}\).

c. What is the probability that the actual tracking weight is greater than the prescribed weight?

d. What is the probability that the actual weight is within \({\rm{.25 g}}\) of the prescribed weight?

e. What is the probability that the actual weight differs from the prescribed weight by more than \({\rm{.5 g}}\)?

The amount of flow through a solenoid valve in an automobile鈥檚

pollution-control system is an important characteristic. An experiment was carried out to study how flow rate depended on three factors: armature length, spring load, and bobbin depth. Two different levels (low and high) of each factor were chosen, and a single observation on flow was made for each combination oflevels.

a. The resulting data set consisted of how manyobservations?

b. Is this an enumerative or analytic study? Explainyour reasoning.
