Answer:
Option B) The area to the right of 35.5
Step-by-step explanation:
Data:
Let the probability of the correct answers be denoted by the letter C.
The probability of no more than 35 defective CD's can be 35 or less. Therefore, it is presented as follows:
P ≤ 35
Let, the probability of more than 44 correct answers can be presented like this:
P > 44
Therefore, combining the two inequalities gives an area at the right of 35.5
Answer:
The mathematical domain includes all real numbers, while the reasonable domain includes only real numbers greater than 2
Step-by-step explanation:
In the real world, length and width only make sense when they are positive. For that to be the case, the width must be greater than 2. There is nothing in the description that restricts the values to integers.
Answer:
about 3.9 lbs
Step-by-step explanation:
18 7/9 lbs - 14 7/8 lbs
convert mixed numbers to improper fractions
169/9 - 119/8
convert to common denominator
1352/72 - 1071/72
subtract numerators
281/72
about 3.9 lbs
Answer: We are 95% confident that the mean income for all residents of this city is between $26700 and $35400.
Step-by-step explanation:
We know that a 95% confidence interval given an interval of values that we can be 95% sure , that it contains the true mean of the population, not 95% of data lies in it.
Given : A researcher is estimating the mean income of residents in a large city. The income variable is usually skewed to the right. She collects a random sample of 25 people.
The resulting 95% confidence interval is ($26700, $35400).
Then, valid conclusion will be : We are 95% confident that the mean income for all residents of this city is between $26700 and $35400.
Answer:
a. A relative-frequency distribution is to a variable as a ___probability_______ distribution is to a random variable. b. A relative-frequency histogram is to a variable as a _____probability_____ histogram is to a random variable.
Step-by-step explanation:
Probability is a type of mathematics which deals with numerical descriptions of how likely an event would occur, or how likely it is that a the occurrence would be true. The probability of an event is usually between 0 and 1,
where 0 represent impossibility and 1 represents the chance of it occurring.
