Answer:
<em>No mode</em>
<u>Skills needed: Mode (Frequency) </u>
Step-by-step explanation:
1) The mode of a set of numbers is the number that appears the greatest number of times.
Example: In the set --->
is the mode since 8 appears 2 times, while the other numbers only appear once.
There are 2 special cases
---> One is where there is more than one mode: (5 and 3 are both modes in this set)
---> Another is where there is no mode () ---> No number appears more than the other numbers.
We are given a dataset of: and have to find the mode.
2) As you can see, there are no numbers repeated (all of the numbers only appear once)
This means there is no mode.
Answer:
The answer to your question is letter D
Step-by-step explanation:
Rational equation
Simplify
Cancel the denominators and expand
3x² + 1 + x² - x = 4x - 4 + 4
Simplify
4x² - x + 1 - 4x = 0
4x² - 5x + 1 = 0
Factor
4x² - 4x - 1x + 1 = 0
4x(x - 1) - 1(x - 1) = 0
(4x - 1)(x - 1) = 0
x₁ = 1/4 x₂ = 1
Answer:
Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.
Step-by-step explanation:
We use the central limit theorem to solve this question.
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation
, a sample size larger than 30 can be approximated to a normal distribution with mean
and standard deviation
So
Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.
