The CLT applet Go to the textbook Web site (www whfreeman com/tp4e) and click on "Statistical Applets." Launch the Central limit Theorem applet. You should see a screen like the one shown here. Click and drag the slider to change the sample size, and watch how the density curve for the sampling distribution changes with it. Write a few sentences describing what in happening.

Short Answer

Expert verified

The population distribution in the applet is right-skewed.

Step by step solution

01

Step-1 Given Information

Given in the question that

we have to Click and drag the slider to change the sample size, and watch how the density curve for the sampling distribution changes with with it.

02

Step-2 Explanation

The sample mean sampling distribution is represented by the applet.

The population distribution in the applet is shown to be right-skewed.

The sampling distribution becomes increasingly bell-shaped and the distribution becomes normal as the sample size increases. In addition, if the sample size is small, the sampling distribution will have the same right skewness as the population distribution.

As a result, the applet's population distribution is right-skewed.

A 10-question multiple-choice exam offers 5choices for each question. Jason just guesses the answers, so he has a probability 1/5of getting any one answer correct. You want to perform a simulation to determine the number of correct answers that Jason gets. One correct way to use a table of random digits to do this is the following:

(a) One digit from the random digit table simulates one answer, with 5=right and all other digits =wrong. Ten digits from the table simulate 10answers. (b) One digit from the random digit table simulates one answer, with 0 or 1 =right and all other digits =wrong. Ten digits from the table simulate 10answers.

(c) One digit from the random digit table simulates one answer, with odd =right and even =wrong. Ten digits from the table simulate 10answers.

(d) Two digits from the random digit table simulate one answer, with 00to 20=right and 21to 99=wrong. Ten pairs of digits from the table simulate 10answers.

(e) Two digits from the random digit table simulate one answer, with 00to 05=right and 06to 99= wrong. Ten pairs of digits from the table simulate 10answers.

The name for the pattern of values that a statistic takes when we sample repeatedly from the same population is

(a) the bias of the statistic.

(b) the variability of the statistic.

(c) the population distribution.

(d) the distribution of sample data.

(e) the sampling distribution of the statistic.

born in the night or was a female?
(a)369513

(b)485513

(c) 116513

(d)116252

(e) 116233

Run a mile During World War II, able-bodied male undergraduates at the University of Illinois participated in required physical training. Each student ran a timed mile. Their times followed the Normal distribution with mean 7.11minutes and standard deviation 0.74minute. An SRS of 100of these students has mean time xยฏ=7.15minutes. A second SRS of size100has mean xยฏ=6.97minutes. After many SRSs, the values of the sample mean x follow the Normal distribution with mean 7.11 minutes and standard deviation0.074minute.

(a) What is the population? Describe the population distribution. (b) Describe the sampling distribution of x. How is it different from the population distribution?

identify the population, the parameter, the sample, and the statistic in each setting

Unemployment Each month, the Current Population Survey interviews a random sample of individuals in about 55,000U.S. households. One of their goals is to estimate the national unemployment rate. In December 2009,10.0%of those interviewed were unemployed
