Question

Conceptual: Circle the best answer(s) as indicated, or (1 Point) The distribution shown in Figure 1 depicts a distribution that is: 1. Skewed Left Not Skewed Skewed Right Normal None of the above 04 06 08 10 Figure 1 2. ( Point) You decided to play the lottery. This lottery is conducted by selecting 6 numbered balls at random, without replacement, from a population of 40 numbered balls. You win if 5 or more of the numbers you picked match the winning lottery numbers. The probability of successfully matching 5 or more of the winning numbers can be calculated using a distribution. Binomial Hypergeometric Normal Bernoulli None of the above 3. (l Point) A 5-Number Summary is a common way to present descriptive statistics for a set of observations and is closely related to which graphical display of data? Histogranm Pareto Chart Pie Chart Box Plot None of the above 4. (1 Point) A bin contains 32 parts, of which you know 12 are d consecutively without replacement. Let Event A be that the first part sampled is bad and Event B be that the second part sampled is bad. From this, we know that A and B are efective. You select a sample of 2 parts Independent Conditional (not independent) Complementary Bernoulli Trials None of the above Scanned with

Answer 1

1. The distribution has a long left tail. Hence, it is a left-skewed distribution.

Correct option: Skewed left

2. The resulting probability can be calculated using a hypergeometric distribution.

3. A boxplot has a 5 number summary which are the minimum value, Q1, Median, Q3 and the maximum value.

Correct option: Boxplot

4. The events A and B are not independent as when the part A is sampled out, the probability of a sample being bad changes. Hence, the correct option is Conditional (Not independent)
