Intro to Statistics Module 5 (A+ Graded 100% Verified) Random Variable Correct Ans: a variable (typically represented by x) that has a single numerical value, determined by chance, for each outcome of a procedure. Probability Distribution Correct Ans: a description that gives the probability for each value of the random variable. It is often expressed in the format of a graph, table, or formula. Discrete Random Variable Correct Ans: collection of values that is finite or counta...

Intro to Stats MCCC Exam Questions with Correct Answers If A denotes some event, what does (complement of A) denote? If P(A)=0.003, what is the value of P(complement of A)? If P(A)=0.003, is (complement of A) unusual? a. What does (complement of A) denote? b. If P(A)=0.003, what is the value of P(complement of A)? c. If P(A)=0.003, is (complement of A) unusual? - Answer-a. Event (complement of A) denotes the complement of event A, meaning that (complement of A) consists of all outcome...

RATIONALE Using the z-chart to construct a 97% CI, this means that there is 1.5% for each tail. The lower tail would be at 0.015 and the upper tail would be at (1 - 0.015) or 0.985. The value of 0.9850 is actually on the z-table exactly. 0.9850 corresponds with a z-score of 2.17. CONCEPT Confidence Intervals 2 George measured the weight of a random sample of 49 cartons of apples. The mean weight was 45.5 pounds, with a standard deviation of 3. To see if the cartons have a significant...

In which of these cases should the median be used? When the data has small variance When data has no outliers When the data has extreme values When the data has nominal values RATIONALE Since the mean uses the actual values in the data, it is most affected by outliers and skewness. So, we only want to use the mean when the data is symmetric as a measure of centrality. When the data is skewed or has extreme values, the median is a better measure since it is not as sensitive to the...

Which of the following is a property of binomial distributions? All of the observations made are dependent of each other. There are exactly four possible outcomes for each trial. The expected value is equal to the number of successes in the experiment. The variable of interest is the total number of successes or failures for a given number of observations. RATIONALE Recall that for the binomial distribution we are concerned with an event occurring (successes) or not occurring (fail...
