Answer: A. The number is a sample statistic because it is a numerical description of all of the passengers that survived.
Step-by-step explanation:
A population is simply similar items or events that a researcher or an experimenter is interested and wants to carry out an experiment on.
A statistic is simply referred to as the piece of information gotten from the population while a sample statistic is the piece of statistical information which a researcher will be able to get from the statistic.
In this scenario, the number is a sample statistic because it is a numerical description of all of the passengers that survived.
Answer:
75%
Step-by-step explanation:
For this case, the first thing we will do is name variables:
a: percentage from ticket sales
b: ticket sales
We have then:
a = 75%
b = (0.75) * (3200) = $ 2400
Answer:
a = 75%
b = (0.75) * (3200) = $ 2400
The amount of ticket sales is $ 2400.
Answer:
38.11%
Step-by-step explanation:
Given that:
Mean (μ) = 75, standard deviation (σ) = 5
Z score is a measure in statistics to determine the variation of a raw score from the mean. It is given by the equation:
To calculate the percentage of students scored between a 73 and 78 (C grade), we need to find the z score for 73 and then for 78.
For x = 73, the z score is:
For x = 78, the z score is:
From the probability distribution table:
P(73 < x < 78) = P(-0.4 < z < 0.6) = P(z < 0.6) - P(z < -0.4) = 0.7257 - 0.3446 = 0.3811 = 38.11%
Answer:
The answer is 10.5
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
14 divided by 6 = 2.33333333
only 6 in a group so you round it
and you get 2
