PS Unit 8 Review

Front

What is the difference between continuous and discrete data?

Back

Continuous data can take any value within a range (e.g., height, weight), while discrete data consists of distinct, separate values (e.g., number of students, number of pizzas sold).

Front

What type of data is represented by the cost of lunch at Burger King?

Back

Discrete data.

Front

What is the probability that the tenth blood donor is the first donor with Type B blood if 11% of the U.S. population has Type B blood?

Back

Approximately 0.0385.

Front

How do you calculate the probability of getting on base a certain number of times in a given number of at-bats?

Back

Use the binomial probability formula: P(X=k) = (n choose k) * p^k * (1-p)^(n-k), where n is the number of trials, k is the number of successes, and p is the probability of success.

Front

What is Barry Bonds' career batting average?

Back

.298 (29.8% of the time he gets on base).

Front

What is the probability that Barry Bonds will get on base 6 times in 10 at-bats?

Back

Approximately 3.58%.

Front

What type of data is represented by the number of pizzas sold each day in Pizza Hut?

Back

Discrete data.

Front

What does the function F(x) = x + 3 represent?

Back

A linear function where for every input x, the output is x increased by 3.

Front

What is a binomial distribution?

Back

A probability distribution that summarizes the likelihood that a value will take one of two independent states and is defined by two parameters: the number of trials and the probability of success.

Front

What is the formula for calculating the mean of a discrete random variable?

Back

Mean (μ) = Σ [x * P(x)], where x is the value and P(x) is the probability of x.
